+#### Configuration changes for repository storages
+
+This version introduces a new configuration structure for repository storages.
+Update your current configuration as follows, replacing with your storages names and paths:
+
+**For installations from source**
+
+1. Update your `gitlab.yml`, from
+
+  ```yaml
+  repositories:
+    storages: # You must have at least a 'default' storage path.
+      default: /home/git/repositories
+      nfs: /mnt/nfs/repositories
+      cephfs: /mnt/cephfs/repositories
+  ```
+
+  to
+
+  ```yaml
+  repositories:
+    storages: # You must have at least a 'default' storage path.
+      default:
+        path: /home/git/repositories
+      nfs:
+        path: /mnt/nfs/repositories
+      cephfs:
+        path: /mnt/cephfs/repositories
+  ```
+
+**For Omnibus installations**
+
+1. Upate your `/etc/gitlab/gitlab.rb`, from
+
+  ```ruby
+  git_data_dirs({
+    "default" => "/var/opt/gitlab/git-data",
+    "nfs" => "/mnt/nfs/git-data",
+    "cephfs" => "/mnt/cephfs/git-data"
+  })
+  ```
+
+  to
+
+  ```ruby
+  git_data_dirs({
+    "default" => { "path" => "/var/opt/gitlab/git-data" },
+    "nfs" => { "path" => "/mnt/nfs/git-data" },
+    "cephfs" => { "path" => "/mnt/cephfs/git-data" }
+  })
+  ```
+
+#### Git configuration
+
+Configure Git to generate packfile bitmaps (introduced in Git 2.0) on
+the GitLab server during `git gc`.
+
+```sh
+cd /home/git/gitlab
+
+sudo -u git -H git config --global repack.writeBitmaps true
+```
