I need the lowest-impact way to allow more than 10 AFP sessions on my OS X Server running 10.5.8. If I buy a boxed retail copy of 10.5.4 Server Unlimited, will I just have to enter the new license key in Server Settings? Is it OK if the version numbers don't match up exactly on this type of upgrade?
The specific product I'm looking at is here on Amazon. Apple product ID MB605Z/A.
