I have upgraded a few R9.0 to R10.x with out issue.
This morning I went to do a R8.1(65) to R10.
I had an irritating surprise.
The first thing I wanted to do was to upload the new R10 PLDS xml license file to the Ipo prior to runnong the upgrade.
I did not get the LICENSE>REMOTE SERVER tab in Manager.
After a period of consternation and making a few calls I find out that you don't get that REMOTE SERVER Tab when connecting to a R8.1 box.
The have to go ahead and blindly UPGRADE the system and then LOAD the LICENSE after the system comes back.
My normal luck would be either the system failed the upgrade and corrupted the files or the meybe the license file wasn't quite right and I could end up with a down system.
This "feature" presents the following issues to me (maybe it's only me)
Normally when you upload the PLDS license into Ipo prior to upgrade, it does a sanity check of sorts on the license.
That didn't happen so I didn't have warm fuzzies about the License
If you CAN load the License file prior to upgrading the following happens:
System starts upgrading, transferring files etc and then about 20 miniutes into it, the IpO reboots, the IpO cmoes back online with the new R10 software and the phones work.
Then the upgrade continues for the usual 1 to 1 3/4 hours of uploading files.
When you can't preload the License file, the customer is down the entire length of the upgrade because when it does it's "early" reboot to the new software, there is no new R10 license file yet. So they are down for the duration
Anyhow, the IpO upgraded without a hitch, I applied the License after the fact and all is well except for the extended downtime.
All this may be obvious to some, but it wasn't to me....
