A successful migration is more than copying files. The service has dependencies, users, data flows and recovery expectations that need to be understood.nn
What depends on the current system?
Map integrations, scheduled jobs, certificates, firewall rules, DNS records and external services.
What does success look like?
Define acceptable downtime, performance expectations and the checks needed before the old platform is retired.
Who owns the service afterwards?
Monitoring, patching, backups, access and incident response should have named owners.
