How to use the V2 to V3 Upgrade categories

Everything related to The Things Network V2 upgrade to V3.

As announced during the opening keynote of The Things Conference 2021, The Things Network is upgrading to The Things Stack V3. Finally!
We call it The Things Network V3 (or just TTN V3).

Later this year the existing TTN V2 backend environment will be retired and no longer be available. Existing V2 applications, devices and gateways will have to be migrated to the new The Things Network V3 environment.

Migration will involve much more than just some copy paste actions.
As the migration impacts the whole The Things Network Community we expect many users will turn to the forum for questions, tips and issues they may run into during the migration.
The ‘V2 to V3 Upgrade’ category and subcategories were created to support this and make it easier to categorize and find information related to the upgrade.
