I decided to put a list of the migration methods that can be useful for migrating to Azure SQLDatabase. By all means it is not complete and if you have any suggestions to expand it – do not be shy.
The current list of the ways that I am considering is here:
- 
SQL Server Management Studio (SSMS) 
- 
BACPAC + SSMS/Portal/Powershell 
- 
SQL Azure Migration Wizard (SAMW) 
- 
SQL Server Data Tools (Visual Studio) + BCP/SSIS 
- 
Azure Data Factory 
- 
Transactional Replication 
- 
Linked Server 
Read on for the details on each method.
