Recover configuration to CUCM 11.5 from DRS backup of CUCM 12.5

[Alex Pashko]

Hello

Is it possible to recover configuration to CUCM 11.5 from DRS backup (must be UCM and CDR/CMR I suppose) of CUCM 12.5? And what about licenses how does this recover affects to licenses of CUCM 11.5 (in CUCM 11.5 we're using traditional licenses , in CUCM 12.5 we're using smart-licenses) 

Thank you in advance.

No. The version for the backup system must exactly be the same on the restore system.
