Mergers and acquisitions, while demanding financial and commercial events, also provide a unique challenge for quality organizations. When two companies combine, one quality system will inherit a second set of SOPs, a second set of CAPA and deviation procedures, and often a second eQMS entirely. The organizations that actively navigate this treats quality integration as a controlled, deliberate program, with an appropriate and approved scope, and making sure that critical information is not lost during the transition.
Rather than immediately pick a “winning” system and migrating everyone, the priority should be continuity, with the goal that each affected site understand which process applies, how complaints are handled, and how serious events get escalated during the transition. Starting with a transition framework will help keep the business running while harmonization takes place following a planned timeline.
When merging two different QMS, there is also the risk of over-customization. When teams try to replicate every legacy form and flow one-to-one in the new QMS, the validation effort can balloon. A configuration-first approach built on templates gets the combined organization to a suitable base format faster, with additional business-specific functions layered in later. Platforms like are designed around exactly this model, offering pre-validated workflows out of the box alongside configurable, no-code workflows that teams can adjust as their processes mature.
A quality integration event of this scale is a massive change control undertaking. Processes are being modified, responsibilities are shifting, and records are moving between systems. Documenting those decisions under a formal change process — aligned to ICH Q10 — means that the merging process can be held under regulatory scrutiny, and quality teams will have a document trail outlining why a particular call was made.
An eQMS with validated change control and quality-event workflows makes this easy to do. ACE ships with validated workflows for change control, CAPA, deviation, investigation, out-of-specification, and effectiveness checks, so the harmonization itself is captured using controlled, auditable records. Additionally, fully customizable workflows are available to be tailored to business specific record types.
One of the most important but also difficult decisions of a post-merger integration is when both organizations arrive with a mature, validated eQMS and the new quality team must decide on which one to stick with. This step can take up a lot of time, but much of the headache can be avoided by using some specific tools.
Begin by running a structured assessment prior to choosing a platform. Start with an honest, side-by-side assessment of both systems: functions covered by platform modules, the maturity of the eQMS platform, validation states, data integrity controls, and how cleanly each platform handles the core quality functions. The goal here is to identify the features that each platform provides, even though teams might find it natural to want to defend incumbent systems. One angle to look at this process complexity rather than eQMS company headcount or revenue — the chosen platform must be able to absorb the combined organization’s most complex workflows, not only the larger company’s.
There are three viable paths when selecting which eQMS to go with, and each decision comes with pros and cons.
A common failure that can occur is incompatible records when migrating two datasets into one system. Before any records move, align the definitions of each record type: what qualifies as a major deviation, what closure requires when an investigation triggers CAPA, and what training evidence is acceptable, etc. A documented crosswalk can be used to connect the different data fields that contain similar types of data and is a practice that ACE clients commonly deploy for their data migrations.
When one ACE client consolidated records from their former eQMS into ACE, they pulled template documents from ACE, compared their existing SOPs against those templates, edited the templates to transfer relevant content, and set aside templates that weren’t relevant to their business. Templates were further reformatted to accommodate unique departmental work instructions, so no institutional knowledge was lost. In a two-eQMS merger, this crosswalk is done from both legacy systems into the target, and it doubles as the evidence trail showing an inspector how quality principles carried through the transition.
Another tool for successful migration is dedicated migration workstreams, which uses link preservation, pre-migration data screening, dry runs, and formal sign-offs in a stepwise fashion before finally executing the data migration. When implemented correctly with guided templates and automated verification tools, this approach is risk-based and aligned to the FDA’s CSA guidance and EU Annex 11— which is vital when reconciling two source systems.
To successfully merge two eQMS into one, the quality unit should assess both systems, choose an integration model deliberately, harmonize record with a documented crosswalk, and complete migrate as a risk-based activity fully recorded as a change control. While switching to a configurable, pre-validated platform like ACE doesn’t remove the hard decisions, it gives the combined organization one controlled environment to host their records and provides the tools needed to completely migrate data from different sources.
