How migrate Bitbucket from 3 diferents servers to another new server

[Manuel Plaza]

Hello,

We have 3 Bitbucket instances (v 6.1.1) in 3 diferents Linux servers (SLES 15) and we want to migrate and consolidate all of them in a new Bitbucket instance (v 7.0.1) in a new Linux server (SLES 15 SP1).

Could you tell me how we have to proceed, please?

Thanks
