I am in the process of upgrading a CallManager Software running Windows 2000 Advanced Server on MCS7845 server from version 4.1(3) sr6 to version 6.0 using a CallManager upgrade CD. it is required that i migrate the existing database on Callmanager 4.1 to 6.0 using the Data Migration Assistant (DMA) utility version 5.1.2b but i encountered some challenges when running the DMA process with both DMA version 5.1.2b and 6.0.
I am using a backup database size of 1.5GB for this migration and i am prompted with the error messages of "modExportDatabase=Failure" , "Could not complete database processing successfully", "Failed to verify Cisco CallManager database and directory backed up data", "The database and/or directory cannot be migrated as they are", "Verification of DB in IDS failed. Retaining the TAR file as it is","The results are : Backup - Successful. Validation - Failed".
I have uninstalled and reinstalled DMA of both versions on several occasions and yet unsuccessful.
Please does anyone have any ideas on this?
