I am about to migrate my old server to a new server with higher specs. This server is a master server with the ISPConfig (i.e. with its interface) installed. The other server is also a master since I am using a master <> master replication. Is there any existing tutorial for this or any information before I proceed? For the meantime, this is what I am planning: - stop replication on both server - backup all databases from master server 1 to new master server 1 that has ISPConfig with interface installed For the email, I don't know how to migrate it. I hope somebody can point me any info here. For the replication on both server, that is, the new server 1 and still the same server 2, can I just resume the replication after changing the master_host by using the command "start slave" after migrating the database? Or do I need to specify the MASTER_LOG_FILE and MASTER_LOG_POS?
Does the master server is only an ISPConfig master (runs ISPConfig GUI and ISPConfig database) or does it run other services locally like websites or email? Moving emails to a new server is quite easy, compared to hosted websites, as all email accounts are in the database only plus the data is all in /var/vmail folder and is owned by the vmail user and group. So moving ISPConfig database to a new server plus copying /var/vmail (while preserving permissions and file ownerships) is enough. In addition, you must run Tools > resync for email part to get spamfilter file created again in Rspamd or amavis.
