My company bought additional ports from Cisco. Cisco emailed me the upgrade code but I am afraid to apply it to our live system. <br><br>I have had no luck with upgrade codes. So far every upgrade code we have been sent had the wrong information in it & the unity system failed to work till we were emailed a new code a whole day later. We can not accept any downtime like that again.<br><br>I wanted to know, could I test out the upgrade code on a test Unity server first? Could I update from 4 to 8 ports on the test server & see if it works first? If sucessful, could I then use the old code to downgrade the dongle from 8 ports back to 4 so I could put the dongle back on our live system & then do the port upgrade on our live system?<br><br>Can dongles be upgraded & then downgraded & then upgraded again? <br><br>Do dongles keep hardware spec information like amount of RAM or Hard drive size?<br><br>
For the record; there are almost never problems like that one you are preparing for.
The code that you have for that dongle will only work on that dongle. Since you can upgrade and downgrade a dongle you can save the current code if you like and revert back to it if you have any problems.
To get your current code go to the Upgrade License tool and click on 'Generate current system code'. Cut and paste that sting to notepad.

In addition, Kimberly, I think that some of the past problems you guys had were in one of two situations: 1. We were doing something 'out of the ordinary' for a customer, and doing things out of the normal process introduces room for error. 2. Problems with upgrades from 2.4.0 to 2.4.5, where IP integration setting changed from None to TAPI.
If this upgrade doesn't fall into that category, you have every reason to be 100% confident.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
