Dsync migration with shared folders

6 Feb 2017

      Hi everyone,
We discovered that the migration path from a VPS to our 2XHP replication
server environment with shared folders should be:

Rsync all domains from the VPS to serverA. Then rsync all domains from
ServerA to ServerB. ServerA & ServerB are in a identical state.
Create an empty directory for the shared indexes
Start dovecot on both machines.

If we did not sync both machines then dsync could not replicate the domains
that contained shared folders.
What is the right migration process for domains with shared folders ?
Regards,
George
