We are having a 5 node foundationdb cluster running in the datacenter, DC1. We need to move this entire foundationdb cluster into a different datacenter, DC2. There is no network connectivity between DC1 and DC2. The foundationdb nodes in DC2 will have different IPs.

Can someone let me know how to change the IP address of all the foundationdb nodes in this case? Downtime is not a problem. I have seen this [documentation](https://apple.github.io/foundationdb/moving-a-cluster.html) . But our case is different than the one that is explained there.

- FoundationDB Version - 6.2.20

Will something like [this](https://forums.foundationdb.org/t/what-is-the-right-way-of-making-a-copy-of-existing-cluster/1930/3) work?

You could also backup/restore the data but it may take a bit long.
