PST and OST Files

Source files

It is not required that you have the Outlook client installed on your migration workstation when migrating PST or OST files as a source. Simply select the PST/OST files option from the Source dropdown menu and configure the software to migrate your PST or OST file(s).

On the Define Users page in Transend Migration Console, enter the path and filename of an existing PST or OST file when migrating from a PST or PST file.

Target files

When migrating to PST files, you will need either a 32-bit or 64-bit Outlook client installed on the migration machine. For optimal performance, we recommend 32-bit Outlook.

If the target PST file not exist prior to migration then Transend Migration Console will create one for you during migration with the name you provide. If the PST file already exists, enter the name and path in the Target field.


PST and OST files are subject to periodic corruption. Transend Migration Console cannot address all potential corruption issues. If you find corruption within the PST or OST file we recommended that you use the Inbox Repair Wizard from Microsoft’s support web site. This tool will attempt to fix the corruption, but it may not make the OST file convertible.
