https://github.com/ipfs/fs-repo-migrations/releases/tag/v2.0.2
This is pretty much a complete rewrite of the ipfs-migrator package.
In version 2.0.0 a major change was made to the way the migrator works. Before, there was one binary that contained every migration. Now every migration has its own binary. If fs-repo-migrations can't find a required binary in the PATH, it will download it off the internet. To prevent that, build every migration individually, symlink them all into one package and then wrap fs-repo-migrations so it finds the package with all the migrations.
The change to the IPFS NixOS module and the IPFS package is needed because without explicitly specifying a repo version to migrate to, fs-repo-migrations will query the internet to find the latest version. This fails in the sandbox, for example when testing the ipfs passthru tests.
While it may seem like the repoVersion and IPFS version are in sync and the code could be simplified, this is not the case. See https://github.com/ipfs/fs-repo-migrations#when-should-i-migrate for a table with the IPFS versions and corresponding repo versions.
Go 1.17 breaks the migrations, so use Go 1.16 instead. This is also the Go version used in their CI, see
