We migrated a virtual server with transactional replication publications to a new data center. We used CommVault server-level replication to move it. We were surprised when all the subscriptions started having the error "The initial snapshot for publication <blah> is not yet available". The servers for the subscribers (push subscriptions) were not migrated yet and there was a local subscription on the migrated server that was also affected.
We fixed the issue, but I am trying to understand why it occurred. The IP address for the migrated server did change, but I don't know enough about replication to know if the IP is used anywhere.
Any suggestions of possible causes?
