Hi every body,
I have cucm 4.1(3) and I want to upgrade to 7.1(2).
I used DMA to export the cucm database and the DMA result is : Validation = Success with Warnings
DMA has generate the lic file : "licupgrade.lic"
I created the answer file to install cucm automatically with a new hostname, administrator login and password : "platformConfig"
During the cucm installation, the software has detected the usb drive that contains all files but the dma import failed.
I have the following error message : "file retrieval failed for unknown reason"
I have seen that I can :
* trie to change the file name of the .tar file
* trie to use FTP with 3CDEAMON
* use SFTP or FTP
But it never works, it still have the issue.
Does someone have an idea ?
