Migrations for the filesystem repository of ipfs clients

These are migrations for the filesystem repository of ipfs clients. This tool is written in Go, and developed alongside go-ipfs, but it should work with any repo conforming to the fs-repo specs.

When should I migrate

When you want to upgrade go-ipfs to a new version, you may need to migrate.

Here is the table showing which repo version corresponds to which go-ipfs version:

ipfs repo version	go-ipfs versions

            1 |  0.0.0 - 0.2.3
            2 |  0.3.0 - 0.3.11
            3 |  0.4.0 - 0.4.2
            4 |  0.4.3 - 0.4.5
            5 |  0.4.6 - 0.4.10
            6 |  0.4.11 - 0.4.15
            7 |  0.4.16 - 0.4.23
            8 |  0.5.0 - 0.6.0
            9 |  0.5.0 - 0.6.0
            10 | 0.6.0 - current

How to Run Migrations

Please see the migration run guide here.

Developing Migrations

Migrations are one of those things that can be extremely painful on users. At the end of the day, we want users never to have to think about it. The process should be:

• SAFE. No data lost. Ever.
• Revertible. Tools must implement forward and backward migrations.
• Frozen. After the tool is written, all code must be frozen and vendored.
• To Spec. The tools must conform to the spec.

Dependencies

Dependencies must be vendored independently for each migration. Unfortunately, dependencies must not be vendored using go modules because we need to support multiple versions of the same dependency (for different migrations).
