Microsoft SQL DMA query

Hi EE,

Does the Microsoft SQL DMA offline the database as it's migrating the database you have selected?

Thank you.

I don't believe it does.

From my research it looks like it does the following:

1)  Analyzes the schema to make sure that you are compatible with the new version.
2)  Deploys the schema to target server
3)  Copies data from source to target.

I see part 3 as insert into target select * from source.  (OR similar to the migrate data task already in place in SQL).

So you there is the potential for getting locks, but shouldn't offline the source database.

With that said obviously try this in your dev environment or offline hours.
