8 DMSes, 3 CLMs, 2 eDiscovery tools, and a records officer who isn't sleeping. We've seen this exact situation.
The acquisition closed last quarter. The integration steering committee asked for a 90-day plan. The records officer of the acquired entity is asking who's responsible for retention now. The 2 GCs aren't aligned on which CLM survives. The new CISO is looking at 16 different identity stores. The CFO is asking why the document-tool spend just doubled.
This is the structural pattern of every post-merger integration involving regulated document estates. The good news is that it's a known pattern with a known programme structure. The bad news is that you have about 18 months to execute it before the second post-close audit cycle exposes the gaps.

What's actually going to break, and when.
| Months | What surfaces |
|---|---|
| 0–3 | 2 CLM teams realise their contract templates are incompatible. The inherited eDiscovery hold isn't bridged to the parent's hold tooling. |
| 3–6 | First combined regulator request lands. The records team improvises across 2 systems. The export takes 3 weeks. |
| 6–12 | The CFO's procurement review notices the document-tool line items doubled and the planned synergies didn't materialise. |
| 12–18 | First combined audit cycle. Gaps in the records-of-record story become a finding. |
| 18+ | The acquired entity's records become "the legacy estate that we'll consolidate eventually." Eventually doesn't come. |
The pattern is consistent. The path through it is structured.
The eighteen-month consolidation programme.
We've helped enough post-M&A CIOs through this to know the shape of the programme. Yours will vary in detail; the structure is reliable.
Months 0–3: Stabilise.
| Workstream | Outcome |
|---|---|
| Identity unification | One IdP across both estates, with the legacy directories proxied. Single sign-on for the combined workforce. |
| Records-of-record decision | Per document type, designate which system is authoritative for the next 12 months. Document the temporary state. |
| Hold bridge | Litigation hold tooling reconciled — no in-flight matters get dropped. |
| Procurement freeze | No new tools added until the consolidation plan is approved. |
Months 3–9: Migrate the hot tier.
The 20% of the document estate that drives 80% of the regulated activity moves to TeamSync first. Active CLM matters, current claims, current trials, current investigations.
| Workstream | Outcome |
|---|---|
| Hot-tier migration | Active records on the platform under TeamSync's audit chain. |
| CLM consolidation | One contract repository; legacy systems read-only. |
| eDiscovery consolidation | One hold-and-collection surface; legacy review tools sunset on schedule. |
| First audit cycle | First combined exam runs against the consolidated audit chain. |
Months 9–18: Migrate the long tail.
The 80% of the estate that's reference-only moves at a steady cadence. Legacy systems are decommissioned in the order their renewal contracts come up.
| Workstream | Outcome |
|---|---|
| Long-tail migration | Records on TeamSync; legacy retention applied; legacy systems shut down. |
| Vendor sunset | 8 DMSes become one. 3 CLMs become one. 2 eDiscovery platforms become one. |
| Cost-savings recognition | The synergy line item the deal model promised actually materialises. |
| Records-officer consolidation | One records function with one schedule, one ledger, one query. |
What changes when the programme finishes.
The eighteen-month version of you would not believe how different this looks at the eighteen-month mark, but it's worth noting.
| Day-zero state | End-state |
|---|---|
| 8 DMSes, 3 CLMs, 2 eDiscovery platforms | 1 platform, 1 audit chain |
| 2 records officers, 2 schedules | One records function, one schedule |
| Combined regulator response in 21 days | Combined regulator response in days |
| 16 identity stores | One IdP federation |
| Document tool spend ~2x pre-deal | Document tool spend ~0.4x pre-deal (after migration cost) |
| Records-of-record question is "which system?" | Records-of-record question is "which document?" |
How customers compare TeamSync for this programme.
The post-M&A consolidation conversation usually compares against 3 patterns: doing nothing (eventually fails), forklift to a single legacy ECM (high-risk, low-value), or building a custom integration layer (most expensive, highest failure rate). The TeamSync pattern wins because it's a platform consolidation, not a tool migration — the records-of-record concept is what consolidates, with the legacy systems being decommissioned rather than re-platformed.
For specific architectural comparisons: - TeamSync vs OpenText — the broadest legacy ECM footprint - TeamSync vs SharePoint + M365 — the M365-first consolidation pattern - TeamSync vs Hyland OnBase — the customised-legacy consolidation pattern
