+"""Shared namespace --> per-tenant namespace migration.
+
+Perform the following steps to migrate:
+
+1. When no files exist (i.e. no Juju environments exist): do nothing
+1a. When no *unowned* files exist: do nothing.
+
+2. When there's only one user: assign ownership of all files to user.
+
+3. When there are multiple users and a `provider-state` file: parse that file
+   to extract the instance id of the bootstrap node. From that instance id,
+   get the identity of the user who deployed this environment (that's the
+   owner of the bootstrap node). Then proceed as in 4, using that user as the
+   "legacy" user.
+
+4. When there are multiple users: create a new "legacy" user, assign ownership
+   of all files and allocated/owned nodes to this user, copy all public SSH
+   keys to this user, and move all API credentials to this user.
+
+There's not a lot we can do about SSH keys authorised to connect to the
+already deployed nodes in #3, but this set will only ever decrease: nodes
+allocated after this migration will permit access from any of the users with
+SSH keys prior to the migration.
