Merging Two Salesforce.com Instances
May 5, 2006
If you have more than one instance of salesforce.com in your company as a result of separate business units, or a merger, this presentation on how to combine two separate salesforce.com accounts into one is for you. This presentation will help you identify and understand some of the complexities, tricks and tools related to this type of migration. This is a complicated initiative, and one that we strongly recommend you consider getting some assistance with.
Updated as of: Winter 07 Release

Hi Joel,
Nice presentation but it would be nice if you listed the order in which tables have to be updated to the master instance in order to maintain referential integrity.

I updated the last slide (#21) in the presentation with a recommended order for updating tables. Hope this helps.

Hi Joel,
Great presentation but is there functionality in the Winter '07 release to help with this?
