I have a 'counter' plugin to autonumber all 'accounts' on CRM 2011.
This will work fine for new entries, but we already have a few thousand accounts that need to also be given a unique number, what's the best way of doing this?
It depends a bit of how the plugin is written and registered. One way is to write a console program that queries the CRM and updates accounts without customer number. You can probably reuse some code from the plugin.
