Migrate Data into Mango (NoSQL) does not appear to be doing anything

Not including the detail of why?
Apologies, not quite following. Please clarify what you mean by that.
Meanwhile, the "Total Processed" shows 23517947 of 23517947, implying it should be completed; but the seconds keeps incrementing, and the Data Point Details is still missing the historical data.
-
Why you had to restart.
I bet that counter doesn't finish even though the migration is done. The timer not getting stopped is caused by the task rejection message you shared. Those tasks never report having finished (as they were never permitted to execute) but the invoker isn't aware. This should be resolved by preventing these tasks from having been rejected.

Ah, the server is on a trailer which had to be moved (and unplugged for the move)
So then what does the "23517947 of 23517947" mean, if the task was never permitted to execute?
-
1 of the 25 executed and probably finished everything.
-
But the data all starts at the time of the upgrade (i.e. installation of NoSQL). IOW, the historical data is not available, was not actually imported.
-
Give Mango a restart, I would expect it shows up.
-
No joy; data still starts at time of upgrade
-
Should I attempt to restart the migration?
-
You could update your NoSQL module before you try. It should permit multiple threads if you do. There should be relevant log messages but it finishing the migration task from each work item. I don't see a reason why it would say it was finished but your data isn't available.
-
Still getting confusing results.
It's still way slower than I would expect (been running over 24 hours; less than halfway through the data, even on the super-duper instance).
But the real confusion is when I look at a Data Point. At some point during the migration, I saw SOME historical data showing up (going back a few days prior to enabling NoSQL). But now when I check the same Data Point, the data starts at the time of upgrade.
Even more confusing, it seems to have introduced a few false zero values in the otherwise reasonable plot.
Could I send you a dump of the old data?

Upon examining the server, I observed all data from the SQL database had been successfully migrated. It was speculated the data that was sought hadn't been in the SQL database, and this is why it didn't appear after the migration.
