What is the size limit for PST file migrations?
There is a size limit to PST file migrations. This is set at 10GB.
If you try to migrate a PST file that is larger than this size, it will fail and report a size error.
Note: Failures do not consume any licenses.
In order to complete your migration, we recommend breaking the PST file down into separate PST files that are less than 10GB in size. Once they are on your Microsoft Azure storage blob, or in the BitTitan storage vault, restart your archive migration project, and follow the instructions in KB004939.
Note: There is an Advanced Option to set licenses consumed to a value higher than the default of 1; refer to KB004941 for more information. For example, if this value is set to 2, we will try to migrate up to 20GB instead of up to 10GB. However, this is subject to disk space availability.
