I have run in to a mysterious upgrade. We are helping a customer to migrate from an old CallManager running 4.1.2. We are using and old MCS 7816H3 as a physical test server. The server is updated to 6 GB RAM.
First step is to use the DMA migration tool, and that worked fine. Installation of the new 7.1.5 server worked just as well. It came up with the correct database, and to test phones were able to boot and worked as expected.
Then we installed the ciscocm.refresh_upgrade_v1.1.cop file, as requested from Cisco, to be able to upgrade to 8.6.2. Installation of 8.6.2 software was done and the server now shows:
Active Version 220.127.116.1100-6
Inactive Version 18.104.22.16800-30
Doing a switch version will actually boot to 8.6.2, but only for 5 minutes, whereafter the server sends a term signal to itself and falls back to 7.1.5 again. One are just able to login to the console, but the server newer succeds in staying on the 8.6.2 software. No messages are seen ...
What is going on? It should be possible to do this upgrade directly from 7.1.5 ?
