    What are you upgrading? SQL Server or the database schema/data?

    I understand this will be a 90% schema upgrade and 10% data that uses the new schema

    In the case of schema/data changes I would take database snapshot if you're using Enterprise edition.

    Yes, it is enterprise edition.

    In case we rollback the upgrade, we need to rollback all of the Principal/Mirror and Log Ship pair. So, although I did want to consider Snapshots I had some questions around it.

    1. If the Snapshot needs to be taken just on the Principal? (Never tried snaps of a Mirror/Log ship secondary)

    2. How much free space would I need to support the Snapshot sparse files?

    3. Do I need to suspend Mirroring/Log Shipping while running the Snapshot?

    4. Will restoring from Snapshot require re-establishing Mirroring and Log shipping?
