NTA settings gone after IMC upgrade

Quick update, I've just set up a single task (interface) but it seems that I can't view it as I could before

Re: NTA settings gone after IMC upgrade


NTA configuration is stored in unba_master database, while flow records/aggregated data (flow statistics and history data) are stored in unba_slave database. Have you restored these?

Please also check the NTA Settings > Traffic Analysis Task Management (rather than the Group Management) and see if there are any of your tasks in the list there.

Upgrading IMC/NTA should not delete anything in these databases (and I haven't seen anything of the sort so far, unless an NTA component was manually Undeployed, which informs you about dropping the database).

Keep in mind that unba_slave is not backed up by default, and requires moving/deleting the unba.skip file in iMC\dbman\etc folder. Hence if you migrate, you would (by default) lose only the historical data and NOT your configurations like tasks, devices etc. Unless you back up and restored that database as well by first moving/deleting the .skip file.

Hi Justin 

Appriciate fast response 

I see the issues now, I haven't moved/removed unda.skip file 

I guess that unba_slave from 7.0 can't be restored on 7.3. It seems I'll have to set this part from the scratch
