Call Manager Migration from 8.6 to 10.5 via DRS Back-ups?

[Dan Rufer]

Is it possible to perform a migration of Call Manager from 8.6 to 10.5 via a DRS back-up?  The same question applied to CUXN, CUPS, & CCX?

We're about to perform such an upgrade.  While the Cisco Prime Collaboration Deployment 10.5(1) application can perform such an upgrade for CUCM & CUPS, it does not look like it can do so for CUXN or CCX.  If that's the case, I'd be tempted to perform standard .IOS installations with a DRS back-up to import if that would work.

Thank you for your guidance.

Hi Dan,

You cannot restore the backup taken on CUCM 8 to CUCM 10.

You opt for PCD to avoid DRS.
