We were upgrading CUCM 8.6 to 10.5 but unfortunately it failed with an error saying there is no disk space available, we opened case wtih cisco & we were advised to perform following tasks to free disk space:
Clear the logs is from RTMT tool, download the old log/traces and delete them from the server with this process: 1) Login to RTMT 2) Go to Trace & log central 3) Select Collect File 4) Select All service checkbox and All server checkbox, click next. 5) Select a period of time. Select all the time frame for the logs that you do not need anymore, example from January until July. (Also there is a drop down so you can clear the ones from the inactive partition.) 6) Select the Delete file Checkbox. 7) Click finish
We followed procedure & after 8 hours it made 6495 MB space free. Before was 36444MB & after process 29949MB.
Reason i mentioned about new ova file for CUCM 10.5 is that while creating VM i will have option to select 7,500 users (this will give me 2x80GB, 2xvCPU, 1x6GB RAM)
I will try installing your suggested cop files & will update you. Do i need to restart Servers after cop file installation ?
