How much disk space is needed on the source and destination servers for migration?
All content, except for databases, is copied directly to the destination server using the
rsync utility. Therefore, the amount of free disk space on the source server must be greater than the size of all databases on subscriptions selected for the transfer.
Note: this requirement applies only for transfer between two Plesk servers. Migration from other panels requires that amount of free disk space is the same as the size of all migrated objects.
The Temp directory specified in a new migration (from the target server) is the one used to store the database dumps and temp files at the source server for later migration to the destination server:
The amount of free disk space on the destination server must be greater, than the total size of subscriptions selected for the transfer. Go to Tools & Settings > Summary Report and select Full Report to see the full size of all subscriptions on the server.
It is recommended to add 5-10G on top of the estimated size of the data. This way, either server will have enough free disk space for other operations.
Three subscriptions are selected for the transfer:
domain1.test has a size of 10G. Among those are two databases - 1.5G and 0.5G in size.
domain2.test has a size of 3G. No databases exist on this subscription.
domain3.test has a size of 12G. Two databases - 2.5G and 1.5G in size - exist on this subscription.
In this case, the source server must have 16G of free disk space (size of all databases + 10G) and the destination server must have 35G of free disk space (size of all subscriptions + 10G).
"... source server must have 16G of free disk space ..."
Should the minimum requirement on the source server of the example not be 18 G instead of 16 G? (DBs with 1.5 + 0.5 + 2.5 + 1.5 plus 12 GB for domain3.test (12 GB) = 18 GB total)?
@Peter, No, content will be moved using rsync command so no space for web content is required.
10GB is being used for logs and temporary files- it is best practices
Someone knows which is the destination path on DESTINATION server in a migration with migration manager?
and if yes, is it possible to change the path? (for space reasons).
Sites content is copied directly to vhosts directory.
As for databases, try this instruction on a destination server: https://support.plesk.com/hc/en-us/articles/115004005493
after migration of one subscription. I check the size ine target server. It is less than the size in the source server.. is that normal ?
