1. Upgrade SCS to the same version as the packages to be installed on RL8 or the OVA images. It is assumed that you are currently at v1.7.1-el7.
   If the existing SCS server is less than 1.7.1, perform the upgrade to 1.7.1. Full instructions for the upgrade can be found here.

2. If static IP addresses were previously assigned before this migration, skip this step and proceed to the “boot/reboot” step (see step 3).

   1. Use case #1: Allow DHCP to assign IP addresses
      When the cluster nodes are rebooted, DHCP will assign an IP address to each node. If the nodes have already been booted with manually assigned IPs, the assigned IP addresses will remain the same. If IP addresses were not manually assigned, but existing DHCP leases are still in effect, then currently assigned IP addresses will remain the same. If existing DHCP leases have expired (or this is the first boot of the storage cluster), DHCP will assign IP addresses from the allocated pool in no particular order. When this use case is selected, proceed to the “Boot/reboot” step.

   2. Use case #2: Pre-assign an IP address to each storage node
      In this case, an IP address must be manually assigned to each storage node before it is rebooted. The procedure for manual assignment is fully explained in Configuring Swarm for Static IPs with Swarm Cluster Services (SCS)).
      The summary of the manual assignment procedure is:

      1. Get an instance list that provides a node ID to use in the next step.

         Code Block
         scsctl storage instance list

      2. Assign an IP address to each node.

         Code Block
         scsctl storage config set -d -i {chassis ID} "network.ipV4Address={your.static.address.here}"

   3. If the storage cluster was previously using static IP addresses defined in SCS 1.5 (or an earlier version), remove the customized node.cfg files for each storage node.

      Code Block
      scsctl storage config file unset -d -i {chassis ID} node.cfg

3. Boot/reboot storage nodes.

4. Create a support bundle. If you run an issue, please contact DataCore Support including the support bundle.

   Code Block
   language bash
   cd /root/dist && ./updateBundle.sh cd /root && /root/dist/techsupport-bundle-grab.sh -U ${SWARM_ADMIN_USER} -A ${SWARM_PASSWORD}

5. Create a backup of the SCS system configuration and Swarm software repo.

   Code Block
   mkdir /root/mig2rl8 scsctl backup create -o /root/mig2rl8/scs_backup_full.YYYYMMDD.tgz
