QlikView tasks not displaying after server migration

J_Mulholland — Mon, 26 Jan 2026 18:19:17 GMT

We have migrated out QlikView April 2020 SR4 environment to new servers (2012-2019) using temporary license keys provided by Qlik. I have followed the migration steps from the Qlik help docs and the "Worry Free Migration for QlikView".

I used the xml DB viewer power tool to update the machine names in the restored QVPR files. When I start services back up i can see the tasks. However after a server reboot or service restart the tasks disappear and I get the "No Tasks to Display" message. Is there something I'm missing?

Hello @J_Mulholland,

Thanks for posting.

When rebooting/restarting the services, do you see any errors on the Distribution/QMS logs and is also the QMS logs reporting any hint about the tasks, like XX tasks saved.

On the other hand, are such environment using a Publisher license? When the tasks have gone, do you still see all the Source Documents listed on its tab on the QMC, if yes, I assume the documents have no tasks associated to the qvw files.

Cheers,

Albert

Thanks Albert.

the only clues in the log files I see are these below-

20220311T094200.842-0500 Information BeginSaveTasks START
20220311T094200.849-0500 Information BeginSaveTasks Handle returned: 83058ba9-f541-4b90-876d-d33dbe85e2e6
20220311T094200.887-0500 Information Tasks reset: Number of QMS tasks differ from number of QDS tasks
20220311T094200.887-0500 Information EndSaveTasks

We do not have a publisher license for the old environment or the new environment. And yes, when the tasks are gone I no longer see the Source documents.

Thanks again Albert. I figured out the problem. I must have misinterpreted the steps. I did not restore all the required files in the QlikTech folder so the task folders were missing from the DistributionService folder. Seems to be fine now
