I have a customer who would like to upgrade its CUCM from 8.5 to 8.6 (I don't know why he wants it), somebody knows when I do a upgrade from CUCM 8.5 to 8.6, all the configuration remains and is valid for the new version? Is a minor upgrade?? How many improvements have the 8.6 about 8.5 version??
In the cisco site, all documentation for the 8.5 version is the same than the 8.6 version, but I didn't find any documentation for this purpose. All the documentation that I can find is about the upgrade from 4.X or 3.X version.
