In Progress Migrated Work Items don't appear in Target Project Default board

[mkennerley]

I have migrated all my work items from one Azure Devops Project into a new Azure Devops Project (in different Orgs).
However, all the work items are not showing on the new defaults boards.
I can see them if i create a new query but not on any of the default views.

I have only migrated the Work Items, iteration and area paths.
What have I missed migrating?
Also, should I have customized the board columns etc on the target to match the source before migrating the work items?

Spent a bit more time trying to work out what has happened.
On my Target Project I have 2 Teams.
The default Team that was setup when the Project was created and another that looks like it was migrated from the Source (Same name as the source team). The Default team has Members and the Migrated Team does not.
The boards that have items are related to the Migrated Team.
The default boards are related to the default Team and have no items.

Should I have done some form of mapping between the source and target teams ??

Looks like I have solved this problem.
My source and target projects were named differently and therefore the Teams were also named differently.
When I did the initial migration I did not do any custom mapping between Project or Team names.
I am not sure if I should have done or how I could do it.

But, I solved it by cleaning my target project (removed all migrated work items, removed migrated team, removed migrated iterations and area paths). Then I changed the name of my source project to match the target project name (the Team name was also renamed).
Then I did the Work Item migration again.

Now all the migrated work items are against the expected team, board and backlog in the target project.

This process ay not work for everyone as I had a simple Source Project so renaming it wasn't a problem.
