Definitely go with C. Incremental backups alone won't cut it for a 50GB database, and a full backup might take too long. Logical migration tools are the way to go!

I'm torn between A and C. Full and incremental backups can provide a reliable fallback, but logical migration tools may be more efficient for a 50GB database.

Option C seems like the best choice here. Logical migration tools can help preserve the database structure and minimize downtime during the migration.
