Move SharePoint Content Databases
Does this support movement of content databases from SharePoint on premise to Azure?
FDT offers optimized file movement, but no specific features for database migration. E.g. it can move your database files or backups, but that’s all. For something more tailored to SQL databases, you may like to look at this, the Azure Database Migration service: https://docs.microsoft.com/en-us/azure/dms/dms-overview. I'm not personally familiar with the database migration service. At a guess I would expect that FDT may move the data more quickly, but the Database Migration Service may actually offer less total downtime (due to doing much of the movement while the databases are still running).
