All of this is very nice, but has anyone noticed that the old customer account number, which is still the required Account Number required when registering MAS, cannot be found anywhere in Atlas? The Registration Number is available, but this is only part of the Account Number (characters 4 through 9). Try to implement a new activation code after you upgrade users or add a module, and you'll notice that the account number doesn't need to be changed.
Now, perform a parallel upgrade and prepare to complete the registration information, and you'll find that the Account Number, if you enter the new account number (beginning with 4), does not work; you must have the original Account Number, which I now write down from the System Configuration window of the existing install before installing the new program, although I have had to access TWO webistes to get the information I need to install MAS 90.
Wow, I feel better now.
