I am working with an organization that has an application with a Sybase database. The vendor of that software has changed the database to MS SQL. Initially, the vendor made a big deal about the migration/conversion process. Since it's the same vendor, I'm thinking that it should not be a big deal. When I asked them what migration tool they are using, they said that they are using straight SQL.
Does that mean that in the development of the new MS SQL database, they used the tables in the entity relationship diagram of the Sybase database, and mapped the new database tables in the MS SQL database, and they used SQL to "transfer" the fields to the new database? ... and as such the migration or the conversion, should be easy with any major problems?
