How to enable velocity report after migration from next gen board ?

[Nilesh Sukalikar]

Hi , I was using next-gen board for 7 sprints. But after I decided to migrate to clasic board.,

I created new classic board and moved all the tasks,stories and bugs to this board. 

After this, All I can see is the sprint is starting from where I left earlier. But, when I go to check my velocity report, it shows nothing for my previous sprints. All reports are empty. How to fix this ?

Hi Nilesh,

As covered in the documentation; "Migrate between next-gen and classic projects", the two project types have a very different architecture:

Next-gen projects and classic projects are technically quite different, so a few things can break when you migrate from a classic software project to a next-gen software project. For example:

• Epic links and issue links: Any issue links in your classic project will not exist in your next-gen project. The issues themselves will still exist, but the links between them won't.

• Subtasks: All subtasks will be lost in this migration process.

• Custom fields: These must be recreated in your new next-gen project.

• Story points estimation: This data will be lost, however you'll be able to start using story points estimation by enabling the Estimation feature in your next-gen project.

And one of the things listed as affected is the Story point estimations and the Velocity Report uses the Story points to calculate the report, so when switching to the new project type the historical velocity is lost due to the differences in how the project types calculate the data.
