I have an SSIS package that moves data from a table into another table in another database. The source table has an identity key.
I need to perform some operations on the data. The only way I can see to do this is to disable the identity key in the destination table and then use the alter table switch approach outlined here: https://stackoverflow.com/questions/1049210/adding-an-identity-to-an-existing-column-sql-server.
Is there an easier way to migrate data, preserve a key and then restart the identity column?
