Avaya to Amazon Connect Migration:
How the 45-Day Automated Path Works

An Avaya to Amazon Connect migration moves VXML applications, VDN routing rules and Experience Portal logic into native Amazon Connect contact flows. Automated discovery platforms read the existing Avaya configuration, generate Contact Flow JSON from it, and complete a traffic-shifted cutover in roughly 45 days instead of the 8 to 18 months a manual rebuild typically needs.

TL;DR
  • Avaya to Amazon Connect migrations fail on discovery, not on build. Most enterprises cannot produce accurate documentation of their own IVR.
  • Automated discovery reads VXML, VDN tables, Orchestration Designer projects and integration hooks directly, removing the four to six week manual documentation phase.
  • Generated Contact Flow JSON preserves the original call logic instead of rebuilding it from a blank canvas.
  • A traffic-shifted cutover moves DIDs in controlled percentages, so rollback stays available throughout.
  • Aumne ACT delivers this in 45 days from a fixed fee starting at $25K, against $200K to $2M on a time and materials manual program.
01 / Scope

What an Avaya to Amazon Connect migration actually involves

An Avaya to Amazon Connect migration is the transfer of call routing logic, self-service dialogue and backend integrations from Avaya Experience Portal, Orchestration Designer and VDN-based routing into native Amazon Connect contact flows.

The work splits into four technical layers, and each carries its own risk. The telephony layer moves DIDs and carrier trunking to Amazon Connect claimed numbers. The routing layer translates VDNs, vectors and skill-based assignments into queues, routing profiles and agent hierarchies. The self-service layer converts VXML applications and speech grammars into Contact Flow JSON with Amazon Lex bots. The integration layer rewires CTI screen pops, CRM lookups and host adapters into AWS Lambda functions.

Enterprises usually underestimate the second and third layers. A routing table that looks like forty VDNs on paper often resolves to several hundred distinct call paths once holiday schedules, emergency overrides and department-level exceptions are expanded. Our Avaya migration page covers how that estate is scoped.


02 / Timelines

Why manual Avaya migrations run 8 to 18 months

The delay is almost never the build. It is the discovery.

A manual program starts with system integrators interviewing subject matter experts to reconstruct what the IVR does. Those experts have often left the business. Orchestration Designer projects have been patched for a decade. Prompts reference product lines that no longer exist. The result is a four to six week documentation phase that produces an incomplete picture, and every gap surfaces later as a production defect.

Traditional programs also carry a staffing problem. A manual Avaya migration typically needs 8 to 14 full-time engineers across telephony, speech, integration and QA. At time and materials rates, that is where the $200K to $2M range comes from, and it is why scope creep is the norm rather than the exception.

03 / Method

How to migrate from Avaya to Amazon Connect: the three-phase method

The method below is how Aumne ACT sequences the work. It is written so you can hold any vendor to the same structure.

Phase 1. Automated discovery (days 1 to 14)

Read-only ingestion connects to the Avaya estate and extracts every flow, VDN routing rule, integration hook and speech grammar. Nothing is modified and no production traffic is touched.

The output is a complete call-path inventory: which paths carry volume, which are dead code, which contain compliance-relevant disclosures, and which depend on backend systems that are themselves being retired. For most enterprises this is the first accurate map of their own IVR in years.

Phase 2. AI transformation (days 15 to 30)

The discovered logic is transformed into native Amazon Connect artifacts. Contact Flow JSON is generated directly from the original routing logic, Lex bot intents are derived from existing grammars and utterance data, and Lambda stubs are produced for each integration hook found in discovery. This is the Amazon Connect migration path in practice.

This is the step that separates preservation from rebuild. A blank-canvas rebuild discards institutional knowledge encoded over a decade. Generation from discovered logic keeps it, then lets you decide deliberately which paths to modernize.

Phase 3. Deploy and evolve (day 31 onwards)

Cutover is traffic-shifted rather than flag-flipped. DIDs move in controlled percentages, both platforms run in parallel, and rollback remains available at every increment.

After cutover the work becomes containment tuning and intent-drift monitoring. Containment is the share of contacts fully resolved in self-service. Aumne reports a typical post-migration containment rate of around 65 percent, against the low twenties that aging Avaya IVRs commonly deliver.


04 / Mapping

What actually maps, and what does not

Not every Avaya construct has a clean Amazon Connect equivalent. Being explicit about this early prevents the late-stage surprises that derail cutover dates.

Avaya constructAmazon Connect equivalentMigration note
VDN and vector routingContact flows and queuesExpands significantly, one VDN often becomes several flow branches
Skills and agent skill levelsRouting profiles and queue priorityPriority and delay values need re-derivation, not copying
VXML applicationContact Flow JSON plus Amazon Lex botDirected dialogue converts cleanly, open-ended speech needs retraining
SRGS speech grammarsLex intents and slot typesGrammar coverage becomes training utterances
AEP announcements and promptsPrompt library or Amazon PollyRecorded prompts can be lifted, TTS is the cheaper long-term path
CTI adapter and screen popAmazon Connect Streams plus LambdaRequires CRM-side work, scope this with the CRM team early

The VXML layer itself is defined by the W3C VoiceXML 2.0 specification, and the destination constructs are documented in the Amazon Connect administrator guide and the Amazon Lex developer guide.


05 / Due Diligence

The five checks to run before you sign a migration contract

  1. 01
    Ask the vendor to demonstrate discovery output on your estate before the statement of work is signed.
    If discovery is billable interviews rather than automated ingestion, the 8 to 18 month timeline is already baked in.
  2. 02
    Require a call-path inventory with volume data attached.
    Migrating dead code is the most common source of avoidable scope.
  3. 03
    Confirm whether the commercial model is fixed fee or time and materials.
    Time and materials transfers all scope risk to you.
  4. 04
    Ask how cutover handles rollback.
    If the answer is a single cutover weekend, there is no rollback.
  5. 05
    Establish the post-launch model in writing.
    Containment tuning after go-live is where the business case is actually realized, and a separate engagement for it changes the total cost materially.

06 / Vendor Risk

What Avaya's restructuring means for your timeline

Avaya has been through two rounds of restructuring, and that has changed the calculus for enterprises running Experience Portal and Orchestration Designer. Support roadmaps, partner availability and specialist skills in the market have all tightened.

The practical consequence is that migration has moved from a discretionary modernization project to a risk-managed dependency. Enterprises that waited are now competing for a shrinking pool of engineers who understand both the Avaya estate and the destination platform, which is precisely the constraint automated discovery removes. This is the pattern we see across enterprise contact center migration programs.


07 / Proof

Proof from a live Avaya to Amazon Connect migration

VIS Networks migrated Workplace Options, an HR and employee assistance provider, from Avaya Vector routing to Amazon Connect. Automated discovery completed in 8 days. Total delivery was 38 days. Thousands of DIDs were migrated, and post-migration containment reached 55 percent. The full write-up sits with our other customer stories.

In a second deployment, Agnoshin Technologies delivered an Avaya to AI-native migration for an African telecom operator in 42 days, lifting containment from 22 percent to 65 percent and producing a 3x first-year return. Both programs were delivered by system integrators using the platform, not by a consulting team rebuilding from scratch.

For the wider picture of how these programs are structured, read our guide to IVR transformation. Platform capability and pricing for the destination are documented in the Amazon Connect product overview.

Frequently asked questions

How long does an Avaya to Amazon Connect migration take?

With automated discovery and flow generation, roughly 45 days from ingestion to production cutover. Discovery runs days 1 to 14, transformation days 15 to 30, and traffic-shifted deployment from day 31. A manual, SME-dependent migration of the same estate typically runs 8 to 18 months.

Do we need Avaya documentation before we start?

No. Automated discovery reads the live Avaya configuration directly, including VXML applications, VDN routing rules, integration hooks and grammars. That removes the four to six week manual documentation phase that manual programs depend on, which matters because most enterprises no longer have accurate IVR documentation.

Can we migrate without downtime?

Yes, if cutover is traffic-shifted rather than a single switchover event. DIDs move in controlled percentages with both platforms live in parallel, so rollback stays available at every increment. A one-weekend cutover with no parallel run has no rollback path.

What happens to our existing speech grammars?

SRGS grammars become Amazon Lex intents and slot types. Directed dialogue converts cleanly because the vocabulary is bounded. Open-ended natural language prompts need retraining against real utterance data, so plan for a tuning window after go-live rather than expecting parity on day one.

What does an Avaya to Amazon Connect migration cost?

Aumne ACT engagements start from a fixed fee of $25K, with the final figure driven by estate size and integration count. Manual time and materials programs for comparable estates range from $200K to $2M, largely because discovery and scope creep are billed as they occur.

Is Amazon Connect the right destination for every Avaya estate?

Not automatically. Amazon Connect suits pay-per-use economics and teams already invested in AWS, with native Lex and Bedrock AI. Google Dialogflow CX is often the stronger fit for very complex state-driven IVR, and Genesys Cloud CX remains a valid choice where the organization is committed to the Genesys ecosystem.
