Missing discussion in migrated work items

[Tatzoof]

Hi,

I made a migration with following options to collapse the history in a json file, but it seems that for some items, it misses some of the discussions. Can't figure out why.
I mean, we can find them in the history, but not properly in the work item (although they were still present in the last revision on Source).

        "MaxRevisions": 1,
        "ReplayRevisions" : false,
        "AttachRevisionHistory": true,

Now it seems also i can't re-run the migrated again with history. It skips them due to dates of last update. I though we were able to get back the history in a second time.

[11:10:33 DBG] RevisionsToMigrate:----------------------------------------------------
[11:10:33 DBG] TfsRevisionManager::GetRevisionsToMigrate: Raw Source 101524 Has 5 revisions
[11:10:33 DBG] TfsRevisionManager::GetRevisionsToMigrate: Raw Target 198238 Has 4 revisions
[11:10:33 DBG] TfsRevisionManager::GetRevisionsToMigrate: After removing Date Matches there are 4 left
[11:10:33 DBG] TfsRevisionManager::GetRevisionsToMigrate: After removing revisions before target latest date 11/11/2022 16:07:09 there are 0 left

Do you see a way for me to bring back the discussion in the work items?

The discussions are part of history. If you want to bring all of the discussions, then you need to migrate all of the revisions.

Migrating all of the Revisions is the default mode described in the documentation for the WorkItemMigatiin processor.

[MrHinsh]

All of the historic being migrated for Work Items is the default mode of the tool.

What history are you finding is not migrated?

I mean, the Discussion part, how could i migrate all the discussion?
I understand is part of the history, but, in my code, i set the attachhistory to true, but it seems there are some missing parts of the discussion, so, i don't understand what are the parameters for it.
Is it possible to migrate it, when all work items are already migrated?

[MrHinsh]

No you cant migrate it afterwards.

Can you share your config?

All looks good, so not sure why. You may have to be debug with a single WI and see what its doing
