Plz, see the attach file.

it is capture display include error message. : Failure, windows-based W1 Migration verification.

I find message that DMA-backup files was made by DMA tool 5.0.4. but it doesn't verification.

Re: DMA problem

Hi Donghwa,

Have you checked this log file, it may indicate the exact nature of the problem;

Data validation log

Contains any validation errors that are found during the verification of database and directory data during the backup process

File Location C:\CiscoWebs\DMA\Bin

File Name datavalidation.log

From this doc;

Hope this helps!

Re: DMA problem

Hello Rob,

Same error message here.

Addition: File datavalidation.log which is supposed to explain why validation failed is not produced in C:\CiscoWebs\DMA\Bin or any other directory on the server.

Any suggestins?

Hi Alex,

I think you should probably open up a case with Cisco Tac. I had a look on the Bug Toolkit and noted 51 Bugs associated with DMA problems on the CCM 5.X train. You might be hitting this one (that does not list any workaround);

CSCsf21021 Bug Details

Headline DMA 5.0(4)ES1.1 backup failed:W1 migration verification & DB in IDS veri

First Found-in Version 5.0(4)

Hope this helps!
