Taking over an existing site with service continuity
A controlled operator transition without a redesign: ownership, restore evidence, shadow operations and reversible cutover.
Taking over an existing site with service continuity
Treat operator change as a controlled service transition, not a redesign. Establish client-owned access and licences, prove a restore in an isolated environment, shadow the existing operations and approve a reversible cutover. Continuity is a risk-management objective, not an unconditional zero-downtime promise.
IT, procurement and marketing owners replacing an incumbent operator without rebuilding the public website.
Evaluation criteria
- Client-controlled domains, repository, hosting, CMS and third-party accounts
- Restore evidence and dependency/licence inventory before accepting responsibility
- Reversible cutover with authority, monitoring and incident contacts
Scope
- Asset, account, licence and operational ownership register
- Isolated restore, baseline journey checks and shadow operations
- Change freeze, handover acceptance, cutover and rollback runbook
Red flags
- Credentials are transferred informally while the incumbent retains sole control
- A backup exists but has never been restored or tested
- DNS or hosting changes start before rollback and licence custody are agreed
Questions to ask the agency
- Which assets will the client own and how will incumbent access be revoked safely?
- Can you demonstrate a restore and critical journeys without sending live emails or transactions?
- Who approves cutover, watches service signals and decides rollback?
Out of scope: Redesign, replatforming, historical defect remediation and unsupported software replacement require separately agreed scope.
Acceptance and working examples
- Before transition, record DNS, certificates, hosting, repository/build access, secrets custody, scheduled jobs, forms, analytics, consent tooling and renewals. Transfer secrets securely; do not publish credentials in a handover document.
- Restore into an isolated environment with live integrations disabled; validate forms, search, content publishing and documents. Record supported and unsupported dependencies and obtain a risk decision, not silent acceptance.
- Shadow current operations, freeze changes by agreement, capture a final backup and approve the cutover window and rollback conditions. Monitor during and after transfer; remove incumbent access only after accepted custody and agreed retention duties.
A sourced example relevant to these criteria — MadeByCat
The managed-service page explicitly says work can start on a platform MadeByCat did not build, following a technical/content audit; it describes staging and rollback planning.
Relevant solution — first-party capability statement
This is a first-party capability statement, not a verified takeover case or proof of uninterrupted operation. Compatibility and responsibility require discovery and a contract.
This example is neither a ranking nor a recommendation of the only suitable agency. Ask other candidates for the same scope and acceptance evidence. A solution statement does not qualify category membership; agency case attribution is not independent verification.
Methodology and editorial note
EWIT prepared these evaluation questions to support buyer decisions; they are not measured outcomes of an agency. Source texts were reviewed for their narrow stated scope; company statements were not treated as independent evidence. No legal or formal conformance audit was performed.
