CUCMv7 upgrade CUCMv8

Hi ,

I am doing a upgrade from CUCMv7 to CUCM8. I have restored the configuration version 7 through DRS, and was sucessfull.

So, I installed the upgrade file in the server to install the CUCMv8, and was installed. Now I have in the CUCMv7 in the active partition and CUCMv8 in the inactive partition, but when I select Switch Version, and I have this message:

"error: Switch version disallowed during Licensing Grace Period Failed to Switch Version and Restart the Appliance"

What should I do?

What is the meaning of this message?

CUCMv7 upgrade CUCMv8

Hi Matthew,

It looks like this bug;

CSCtb86875 - Upgrades are prohibited during License Grace Period



After Disaster Recovery System (DRS) backup is done on the old server, we DRS restore all the data into the newly replaced server. The license file for old server is valid for 30 days.

During license grace period, you can not proceed due to the upgrade error message "Upgradeds are prohibited during License Grace Period".


It only occurs after DRS backup and restore data to newly replaced servers.

One example of an erroneous document:

The problem is steps 7-9.  The order should be:

7. install the same version

8. restore the DRS backup

9. upload the new license file


If license is uploaded before DRS restore then use the following steps to correct the state of licensing on the system:

1. Remove the rehosted (new) license files using cli commond "file delete xxx.lic"

2. Restart license manager.

3. Re-upload the rehosted (new) license files.

CUCMv7 upgrade CUCMv8

Hi Rob,

I have the similar scenario, I installed CUCM UNRST on new hardware and restored the backup, after restore I inserted the rehost licenses.

Now when I try to start the upgrade "Upgrade Install" returns (Upgrades are Prohibited During Licensing Grace Period).

I need to do the same workaround?

Also this happened to me and I had to open a case so a TAC guy connected to my CUCM using root access and deleted a file in the licensing folder and then it started working properly.

Hi Cecilia,

Thanks for information, I open the tac and solve the problem.


CUCMv7 upgrade CUCMv8

Do you remember how TAC solved this problem? I got the same issue, and this was my process. I'm upgrading from on MCS to 8.6 on UCS.

1. DRS backup production on MCS

2. Install on a VM. Yes, I get that it's not supported, but it should still work. I've done numerous upgrade from 4.x to 7.x on a VM to 8.x, and it always worked.

3. DRS restore

4. Now trying to upgrade to 8.6 and getting this error "Upgrades are prohibited during Licensing Grace Period"

It's gotta to be some simple trick with license files that could fix this. I tried installing rehosted NODE/PHONE license to the license mac, that didn't help. I tried removing all licenses, that also didn't help.

Do you remember what was the trick?

Re: CUCMv7 upgrade CUCMv8

Hi Roman,

I did have the same problem, for solve the problem was necessary removed all old license files in database informix the CUCM. I opened the case in TAC because is necessary root account to delete files in database.
