Hi
If you are using vSphere replication to replicate, please refer following article for instructions --> VMware Knowledge Base
Note: Step.1: Instead of renaming VM file names of target copy, you can rename the VM folder name and then stop replication
If vSphere replication is version 8.3 with source ESXi hosts running on 7.0 and target ESXi hosts on a minimum 6.5, you can increase the disk space of a replicated VM online without stopping replications.
