Can I merge user accounts?

[booher04]

Is there an easy way to merge user accounts together?  We have an AD integration for users, however our ServiceDesk here has the ability to create users if they can't find them in the system.  We've ran into some duplicate users(which have records associated to them) with the same email address, but different spellings, different info, etc.  Is there a way to take say 3 user accounts(all same email) and merge the data together to one account?

You will not be able to merge user accounts, the best way would be to pick the user the account the user would be using, map all the existing records with the new user, let’s say if it’s an incident record, update the caller field. This can be done using a script to remap all records at once. Also to avoid duplicates in future, you should have a unique key based on which the user record should either get created or updated instead of creating a duplicate id.
