Unable to restore Backup from UCM6104 to UCM6204


Hello everybody.
Recently my UCM6104 crushed so I’ve been sent a brand new ucm6204 as a replacement. I’ve upgraded the firmware from 16 to 18 (I’ve bypassed the wizard) and I’ve tried to restore my backup . No success. The display shows my old IP but I can not even ping this address. I have to reset to factory default so I return back to . I ve tried several backup files but same lack. Do you have any suggestions?!
Thank you in advance


Did you try both network ports?
What was the firmware of the old one (needs to be the same)


If you don’t know what firmware it was on, you may be able to open a ticket, give them the backup and helpdesk might be able to see.
