Hi, We have multiple windows server versions (2003, 2000, 2008, 2008R2 ...) which all have been (wrongly) installed using open license keys Since those servers are used in a datacenter and used by customers we need to change those licenses to SPLA licensing Do we need to change the license on the servers or is the fact that we bought the SPLA sufficient ? If we need to change the licenses to SPLA, then how can we do this ? Thanks in advance ! Kind Regards Stijn

Hello, i suggest to call Microsoft support as licensing is always special within Microsoft. They will gave you the correct information and can also help you with the product key change if necessary.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
