Hi,
Currently we are using FME on Win 2008 R2 server, we are planning to move to WIN 2012 R2 server. Please let us know if we can use the same FME license on WIN 2012 R2 server and if not please provide the contact from where we can get the updated license file.
When reinstalling FME you will need an updated license file that corresponds to the new machine/OS combination.
You should normally ask your local FME partner to help you out with the license file update, you can find a list of all the FME partnes here: https://www.safe.com/partners/partner-locator/
If, for some reason you have further questions about who to contact, you should contact Safe support (e.g. using the Live Chat box at the bottom right of each page here), and they'll help you out.
