Hi All,
We have a stand alone site with 2951 running CME 7.1 and NME-CUE 3.2 running on it.
Due to capacity issues, we have decided to upgrade the router to 3925, however retained the CUE module to re-use it.
Now, that I have installed new router with CME 8.6. I want to upgrade CUE to 8.6 as well.
I understand it has to be a two step upgrade (if i am wrong here, correct me).
TAC has advised me to upgrade CUE to 7.1.7 and then to 8.6.
I have gone through upgrade guides. I am bit confused in terms of the procedure.
I want to go with upgrade method, without wiping out the existing data.
Can some one give me clear steps, how to go ahead with this.
Thanks a ton in advance.
Cheers,
Sami

You can avoid the two step upgrade to save time and aggravation.
Backup data and config, then install 8.6.1 from scratch (tftp installer).
Then restore from backup.

Thanks for the reply Paolo.. Happy New Year
I went through the release notes of 8.6.1 again and did upgrade to 8.6.1 directly from 3.2.5
We performed upgrade on Christmas eve and it was successful at first shot, without erasing any data or any errors.
I haven't heard of any issues post upgrade. I guess, that was perfect.

Hi Samiualla,
Did you done the direct upgrade or Clean upgrade and restore the backup?
We have a 7.0 to 8.6 upgrade soon, i already procured the license. How long it took to complete the upgrade and upload the license?
tnx

Hi Bobby,
I did go for direct upgrade without erasing any existing data. Hence, i didn't have to restore it. However, it is necessary that you have a copy of backup data. Software upgrade and uploading the license files will take an hour or so. Since you need to reload the unity express couple of times.

Sami
