Hi Ali,

The upgrade from 7.1(3) to 8.6(2a) is a direct upgrade path as shown;

Check out Table 4:

So you won't have to run a multiple hop upgrade, but the move to 8.6 does incorporate

a new "Refresh" upgrade portion (see below)

You will have to determine what version you current servers will support this is the "master" list for Server support;

Supported Cisco Unified Communications Manager Releases by Server

Check out this great doc from Saurabh for the refresh upgrade notes for the final step to 8.6.

This Refresh Upgrade will also apply to your CUCM 8.6 final step;

And read great the attachments from Ryan




EDIT: hey Alex ...hope all is well! +5 for this and for trumping my horrendous typing skills
