Exchange 2003 Cals
Posted on 2009-04-15
We currently have an exchange 2003 server installed on an exchange 2007 standard license (we have a mix of 2003 and 2007 cals which is why we still use 2003). We are hitting the database size limit so we want to upgrade our 2007 exchange server license to the enterprise edition.
My questions are:
1. I'm assuming there is no problems installing exchange 2003 enterprise with a 2007 enterprise server license?
2. Do I need to upgrade my mix of user cals (250 in total) to enterprise editions, or can I carry on using my standard edition cals?
