-**This guide explains how to migrate to 0.8 if you have an existing 0.7 cluster.
-We don't recommend trying to migrate to 0.8 directly from 0.6 or older.**
-
-**We make no guarantee that this migration will work perfectly:
-back up all your data before attempting it!**
-
-Garage v0.8 introduces new data tables that allow the counting of objects in buckets in order to implement bucket quotas.
-A manual migration step is required to first count objects in Garage buckets and populate these tables with accurate data.
-
-The migration steps are as follows:
-
-1. Disable API and web access. Garage v0.7 does not support disabling
-   these endpoints but you can change the port number or stop your reverse proxy for instance.
-2. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`,
-   check the logs and check that all data seems to be synced correctly between
-   nodes. If you have time, do additional checks (`scrub`, `block_refs`, etc.)
-3. Check that queues are empty: run `garage stats` to query them or inspect metrics in the Grafana dashboard.
-4. Turn off Garage v0.7
-5. **Backup the metadata folder of all your nodes!** For instance, use the following command
-	if your metadata directory is `/var/lib/garage/meta`: `cd /var/lib/garage ; tar -acf meta-v0.7.tar.zst meta/`
-6. Install Garage v0.8
-7. **Before starting Garage v0.8**, run the offline migration step: `garage offline-repair --yes object_counters`.
-   This can take a while to run, depending on the number of objects stored in your cluster.
-8. Turn on Garage v0.8
-9. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`.
-   Wait for a full table sync to run.
-10. Your upgraded cluster should be in a working state. Re-enable API and Web
-    access and check that everything went well.
-11. Monitor your cluster in the next hours to see if it works well under your production load, report any issue.
