Patching existing databases

Sep 18, 2009 at 4:12 AM

I would like to ask for suggestions as to the best way to create a patching engine, as suggested by mtherien.

In essence, once a database ( say version_1.0 ) has been deployed to production, any changes to the database from there on out will need to be deployed as patches.

The idea that I have is to create a set of patches for each deployment target, which will be run on deployment. (i.e. run patch_1.1, patch_1.2 etc)

In this way, the upgrade path from version_1.0 to 1.1 and 1.2 can be easily re-created and will provide a repeatable way of testing patches.

I am interested in any ideas anyone might in this regard ?
