 If you think a merge request should go into an RC or patch even though it does not meet these requirements,
 you can ask for an exception to be made.
 
-Go to [Release tasks issue tracker](https://gitlab.com/gitlab-org/release/tasks/issues/new) and create an issue
-using the `Exception-request` issue template.
-
-**Do not** set the relevant `Pick into X.Y` label (see above) before request an
-exception; this should be done after the exception is approved.
-
-You can find who is who on the [team page](https://about.gitlab.com/team/).
-
-Whether an exception is made is determined by weighing the benefit and urgency of the change
-(how important it is to the company that this is released _right now_ instead of in a month)
-against the potential negative impact
-(things breaking without enough time to comfortably find and fix them before the release on the 22nd).
-When in doubt, we err on the side of _not_ cherry-picking.
-
-For example, it is likely that an exception will be made for a trivial 1-5 line performance improvement
-(e.g. adding a database index or adding `includes` to a query), but not for a new feature, no matter how relatively small or thoroughly tested.
-
-All MRs which have had exceptions granted must be merged by the 15th.
+Check [this guide](https://gitlab.com/gitlab-org/release/docs/blob/master/general/exception-request/process.md) about how to open an exception request before opening one.

 [storage-paths]: repository_storage_types.md
 
+#### Rollback
+
+There is no automated rollback implemented. Below are the steps required to rollback
+from each storage migration.
+
+The rollback has to be performed in the reverse order. To get into "Legacy" state,
+you need to rollback Attachments first, then Project.
+
+Also note that if Geo is enabled, after the migration was triggered, an event is generated
+to replicate the operation on any Secondary node. That means the on disk changes will also
+need to be performed on these nodes as well. Database changes will propagate without issues.
+
+You must make sure the migration event was already processed or otherwise it may migrate
+the files back to Hashed state again.
+
+##### Attachments
+
+To rollback single Attachment migration, rename `aa/bb/abcdef1234567890...` folder back to `namespace/project`.
+
+Both folder names can be generated by the `FileUploader.absolute_base_dir(project)`, you
+just need to switch the version from the `project` back to the previous one.
+
+```ruby
+project.storage_version
+# => 2
+
+FileUploader.absolute_base_dir(project)
+# => "/opt/gitlab/embedded/service/gitlab-rails/public/uploads/@hashed/d4/73/d4735e3a265e16eee03f59718b9b5d03019c07d8b6c51f90da3a666eec13ab35"
+
+project.storage_version = 1
+
+FileUploader.absolute_base_dir(project)
+# => "/opt/gitlab/embedded/service/gitlab-rails/public/uploads/gitlab/gitlab-shell-renamed"
+```
+
+##### Project
+
+To rollback single Project migration, move `@hashed/aa/bb/aabbcdef1234567890abcdef.git` and `@hashed/aa/bb/aabbcdef1234567890abcdef.wiki.git`
+back to `namespace/project.git` and `namespace/project.wiki.git` respectively and switch the version from the `project` back to `null`.

+#### Implementation Details
+
+##### Avatars
+
+Each file is stored in a folder with its `id` from the database. The filename is always `avatar.png` for user avatars.
+When avatar is replaced, `Upload` model is destroyed and a new one takes place with different `id`.
+
+##### CI Artifacts
+
+CI Artifacts are S3 compatible since **9.4** (GitLab Premium), and available in GitLab Core since **10.6**.
+
+##### LFS Objects
+
+LFS Objects implements a similar storage pattern using 2 chars, 2 level folders, following git own implementation:
+
+```ruby
+"shared/lfs-objects/#{oid[0..1}/#{oid[2..3]}/#{oid[4..-1]}"
+
+# Based on object `oid`: `8909029eb962194cfb326259411b22ae3f4a814b5be4f80651735aeef9f3229c`, path will be:

+```
+
+They are also S3 compatible since **10.0** (GitLab Premium), and available in GitLab Core since **10.7**.
