+## Recabling Maintenance
+
+!!! warning "User Action Required"
+
+    Please read the following information carefully and follow the provided instructions.
+
+We are in the
+[process of becoming `Alpha Centauri` a Stand-Alone Cluster](#becoming-a-stand-alone-cluster).
+Planned now is the integration of the cluster into the InfiniBand infrastructure
+of the new cluster [`Barnard`](barnard.md).
+
+!!! hint "Maintenance Work"
+
+    On **June 4+5**, we will shut down and migrate `Alpha Centauri` to the Barnard Infiniband
+    infrastructure.
+
+As consequences,
+
+* BeeGFS will no longer be available,
+* all `Barnard` filesystems (`/home`, `/software`, `/data/horse`, `/data/walrus`) can be
+  used normally.
+
+For your convenience, we already have started migrating your data from `/beegfs` to
+`/data/horse/beegfs`. Starting with the downtime, we again synchronize these data.
+
+!!! hint "User Action Required"
+
+    The less we have to synchronize the faster the overall process. So clean-up
+    as much as possible as soon as possible.
+
+Important for your work is:
+
+* Do not add terabytes of data to `/beegfs` if you cannot "consume" it before June 4.
+* After final successful data transfer to `/data/horse/beegfs` you then have to
+  move it to normal workspaces on `/data/horse`.
+* Be prepared to adapt your workflows to the new paths.
+
+What happens afterward:
+
+  * complete deletion of all user data in `/beegfs`
+  * complete recabling of the storage nodes (BeeGFS hardware)
+  * Software+Firmware updates
+  * set-up of a new WEKA filesystem for high I/O demands on the same hardware
+
+In case of any question regarding this maintenance or required action, please do not hesitate to
+contact the [HPC support team](../support/support.md).
