My unity is 2.46 with ex55 in-box installed. We are going to upgrade it to a 3.15 unity by setting up a new. New server is win2000 with ex55. I have 2 questions here:
1. I am reading the Cisco upgrade process documentation, one of the step is to import winnt accounts into ex55. Because I still have to restrore message store, my question here is which step is first, import WINNT accounts or restore message?
2. In worst case, if my setting up new server failed, how can I go back to unity 2.46.because I realized that during the upgrade, the licence key(activation code)will be changed to new version 3.15 which means I lost 2.46 license key(activation code)? Can I just reattach the license key back to unity 2.46 server and use upgrade license utility or actually more complex?
Thanks for your answer in advance.
