What is the size limit for Portable Storage Table (.pst) file migrations?

Answer:

The file size limit for PST migrations is capped at 10 GB per file. If you try to migrate a PST file that is greater than 10 GB in size, it will fail and MigrationWiz will report a file size error. Keep in mind that licenses are not consumed when a migration fails.

In order to complete your migration, you must divide the PST file down into separate PST files that are each less than 10GB in size each, and then using the advanced option to increase the license consumption for each item in the migration project. Read the How do I enable consumption of multiple licenses for a single item? article for more information.

Once the PST files are on your Microsoft Azure storage blob, or in the BitTitan Azure storage, restart your archive migration project, and follow the instructions in the How do I import files from Azure into my MigrationWiz project? article.
