Now my question, how can I do this migration without taking the database down at all? Like for example setting something between the two servers as replication or so, so I have exactly identical database up-to-second on both servers, then I can just take the main services down for 1 minute, changing the IP address of the database connection from old server to new server and I be sure that the new server has identical copy of the old one. Restore or Migrate an exported subsite as a standalone siteI have a production server running SQL Server 2008 Web Edition, and it has to keep running 24x7 with almost no down time, and it's the time for us to move to a more advanced server hardware, also it's a good chance to move to SQL Server 2012 Enterprise.Import a backed up standalone site into the Network.No known limitations beyond those of normal BackupBuddy.Import an exported subsite into the Network.It is still included in the main Network backup however. Limitation: The main Network site cannot be exported as it is tied to the Network.Exported subsites may be imported back into the same network (AKA Duplicated), imported into another Network, or restored as a standalone WordPress site using the importbuddy.php tool.If you have access to modify these settings, Maximum PHP runtime is a key setting to increase as needed. Most shared hosting does not permit increasing these resources so BackupBuddy may not be able to finish migrations under these conditions. This can demand more server resources or more PHP runtime. Limitation: As a Network can contain many subsites, each subsite increases the amount of time needed to perform a migration, especially if the sites are large.Limitation: You cannot change from sub-domains to sub-directory URL structure using BackupBuddy Multisite nor can you change from sub-directories to sub-domain URL structure.If the URLs or paths of subsites need to be updated you may perform this procedure by using the 'Mass Database Text Replacement' tool on the 'Server Information' page within BackupBuddy for each subsite you need to update. Due to technical reasons, BackupBuddy currently will not automatically migrate URLs or paths of any other subsites within the migrated network. Limitation: When migrating a Network to a new server or changing URLs, domains, or moving a Network in or out of a subdirectory, BackupBuddy will only migrate the database tables associated with the MAIN site.Migrate entire Multisite Network (different server or URLs) - Use Caution Most shared hosting does not permit increasing these resources so BackupBuddy may not be able to finish restores under these conditions.
Restore entire Multisite Network (same server & URLs) WordPress 3.5 Multisite has introduced multiple problems with site imports related with both file uploads and user imports.Most shared hosting does not permit increasing these resources so BackupBuddy may not be able to finish backups under these conditions. As a Network can contain many subsites, each subsite increases the amount of time needed to perform a backup, especially if the sites are large.
