Do you need to just re-IP the Management IPs or the vSAN and everything else also?
Is the vCenter stored and running on this vSAN cluster or somewhere else?
If it is running on the vSAN then you likely need to be a bit more careful and/or a bit better at CLI to fix the network if you break it (as if you cause the vCenter to become unavailable due to partitioning the cluster then it is host client and CLI, no vDS configurable).
So, changing the Management is fairly trivial, only thing to note with regard to vSAN is that you may want to disable unicastagent updates (# esxcfg-advcfg -s 1 /VSAN/IgnoreClusterMemberListupdates) on all nodes just in case they get removed from the vSAN cluster - NOTE, revert this (# esxcfg-advcfg -s 0 /VSAN/IgnoreClusterMemberListupdates) on all nodes before changing vSAN IPs (as if you don't, the nodes won't know about the new vSAN IPs) - alternatively you can just do each host 1 by 1 with Maintenance Mode 'Ensure Accessibility' option chosen (and don't need to worry about setting/unsetting ignore updates).

With regard to the vSAN IPs - you need to be careful if the vCenter is running on the vSAN cluster - the least risk way is actually just to add an additional vmk tagged for vsan traffic to all nodes (in the new IP range), then validate that it is functional by placing one node in Maintenance Mode with 'Ensure Accessibility' option, untagging vsan traffic on the original vmk and validating that it stays in the cluster (e.g. going over the new network) this can be checked via the CLI (esxcli vsan cluster get) or the vSphere UI Cluster > Monitor > vSAN > vSAN Health > no checks regarding network, ping or cluster should be red , take the host out of Maintenance Mode.
Proceed to do this until all the hosts are using the new network and then simply remove the original vmks that are no longer tagged for vSAN traffic
