We are about to start our journey on migrating our OES2.3 servers to
OES11.1 using the Transfer ID. We have used this process before many
times for migrations and my question is not really about that process,
but more on the planning for roll back in case something goes wrong
during the Transfer ID.

According to the documentation, it is advised to perform an eDir backup
prior to start. Since both our source and target servers are on VMware,
we were discussing shutting down both source and target to get a cold VM
snapshot prior to the Transfer ID process.

Since I have never rolled back a server from a VM snapshot before with
eDirectory, could this introduce issues into our eDirectory environment?

Any insight would be appreciated.
