Hi,

Quoting Thomas Vogt <tv@xxxxxxxxx>:

Hi

I've to move a large cyrus entity from one facility to another with no
or at least a little downtime.

I thought I setup a second cyrus entity on my new data center and use
cyrus replication to transfer all data to this new cyrus slave. After
all mails are copied, the slave will become the primary backend server
for a couple of hours. At this point I'll transfer my cyrus master to
the new location (physical).

After everything is done, how do i copy all new mails from the slave
back to my master who was offline for a couple of hours?

Short answer: as before.
Long answer: at the time you make the slave the primary backend, you configure cyrus to ceplicate back to the old server. Cyrus will log all actions and will catch up when the old server is back online.
