Change a webserver Mirror to Main webserver

Please tell me if I'm doing this correctly. I run a multiserver set up with webservers, db servers, mailservers & ispconfig control panel all separated with mirrors for each. I need to remove an existing webserver A and replace it with a webserver currently assigned as its mirror B. Please tell me if I am correct that I can do this by:

1. In ispconfig control panel, Server Services, change mirror B to Is mirror of Server None.
2. Updating the ispconfig control panel database:

• Backup db first
• next get the id of each server from server table
• change server_id of each site that was on server A to server_id of mirror B
• update web_domain set server_id=<server_id of mirror B> where server_id=<server_id of server A>

3. Update server_id in ftp_users table
4. Update server_id in aps_instances table
Do the same changes (2-4) in the ispconfig database on mirror now webserver B.
Remove server A.
That should be it.

Am I missing anything?

Thanks,

 

You may want to change web_backup, web_folder, and web_folder_user, too.

 

Thanks! Much appreciated. We don't use those features but will update as well.
