### Can I set up a Disaster Recovery site and transfer current licenses on the DC Cluster site to a license server?

There is an Active/Passive cluster setup in the primary DC having perpetual ICS licenses hosted on ISA6000 hardware appliances. They are now setting up a Disaster Recovery (DR) site where they will be setting up another appliance and want the flexibility to re-allocate licenses when required using a license server. They also wish to transfer the current licenses on the DC cluster to a license server and purchase additional licenses. Is this possible?

**A.** With MBR license, hardware appliances with perpetual or subscription licenses could ‘share’ these ‘up’ to the license server which could then distribute them as normal – either back to the same appliance or share them to others; a DR appliance for example.

### Can we surrender the current perpetual licenses on the hardware cluster and transfer them to a new license server?

**A.** Assuming the MBR exists for ISA platform, then yes; the licenses stay installed on the hardware cluster, but each day (configurable interval) the hardware appliance lend their licenses to the license-server, for it to lease out as normal, as if they were installed on the license server.

The hardware appliance can ‘pull them back’ if needed, and if the license-server goes offline the licenses will still be on the hardware cluster.

:::hint{type="info"}
\- The licenses surrendered by the license client to the license server is valid for a period of 10 days.
\- Every lease interval (of 4 hours), the time gets updated to 10 days (from the last successful contact with the license server).
\- In addition to on-demand recall,
  - In case, the license server becomes unreachable, the license client automatically takes back the surrendered license, if the license server is not reachable for > 10 days.
  - Similarly, the license server also removes the surrendered license from its license pool, if the license client did not contact for >10 days.
\- To forcefully take back the licenses, the admin has to remove the license server config on the license client.

### "Exceeded maximum users for this realm. Please contact your system administrator"

Imported config from the current cloud VM on a fresh hardware appliance (in remote DC, no console server yet….). No licenses are installed yet (so limited to 2). On both admin realms, getting the message: "Exceeded maximum users for this realm. Please contact your system administrator".

**A. Workaround**: The issue is due to limiting the users for a realm (User Realms > Users > Authentication Policy > Limits). So, use “Super Admin” session to install required licenses (EVAL will do).
