I have done some ALM server migration for customers. The project data is easy, but the user accounts is problem. So I developed a simple Excel utility to do that for me. I have used this tool in some customer's production environment.
Before use this utility, just make sure you were familiar with Excel VBA language. You need to open the Excel VBA IDE and change some ALM login information in the code. I did't translate the comments to English.
I also wrote a user guide for this utility if you want to know how to use it.
Remember you should test this utility on your test environment before use it on PRODUCTION. you can use it but on your own risk!
