<div dir="ltr"> We are going to migrate the CUCM from 6.0.1 to 7.1.1. The new CUCM 7.X will be installed on a new MCS hardware.<br>The problem is how to migrate the data of the previous CUCM 6.x<br><br>I know we have to use DRS to take the backup of the CUCM 6 to do this. But will the CUCM 7.x will accept the DRS of the CUCM 6.0.1.<br>
Or <br><br>We have to upgrade the CUCM 6.0.1 to atleast 6.1.3 then to 7.1.1. Then take the DRS and push the DRS to the new installed CUCM MCS server.<br><br><br></div>
