Currently, it's not possible to migrate (or have your data moved) from one regional instance to the other. A new team will need to be set up in the correct instance and your data will need to be sent there.
If you are an Enterprise customer and want to move, please get in touch with your account’s Technical Customer Success Manager (TCSM), if you are a free or pro-tier customer please sign up here: honeycomb.io/signup
If Honeycomb Support can help with any part of this process, don’t hesitate to get in touch with your questions at: support.honeycomb.io
