How much disk space is needed for migration on source and destination servers

Applicable to:

  • Plesk 12.5 for Linux
  • Plesk Onyx for Linux
  • Plesk Onyx for Windows
  • Plesk 12.5 for Windows

Question

How much disk space is needed on source and destination servers for migration?

Answer

Source server

All content, except for databases, is copied directly to the destination server using rsync utility. Therefore, 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.

Destination server

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 full size of all subscriptions on the server.It is recommended to add 5-10 Gb on top of the estimated size of the data. This way, either server will have enough free disk space for other operations.

Example

Three subscriptions are selected for the transfer:

• domain1.test has size of 10G. Among those are two databases - 1.5G and 0.5G in size.

• domain2.test has size of 3G. No databases exist on this subscription.

• domain3.test has size of 12G. Two databases - 2.5G and 1.5G in size - exist on this subscription.In this case, source server must have 16G of free disk space (size of all databases + 10G) and 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
