After I renamed my SSIS package within BIDS, the system appears to do the following behavior that I wouldn't have ever guessed: Maintain two copies of the EXACT same DTSX file as I go along - one with the 'old' package name, one with the 'new' package name.
So if I last opened BIDS and edited my package on Friday at 4 PM, I see TWO dtsx files, both last edited at Friday at 4 PM. One with the slightly different old name (representing a moment that I made a typo and then decided to re-name the package to correct it, inside BIDS), and the other one with the current name of the package - the one that's been current for quite a while now.
Is this normal?
