If you run out of disk space, you can seamlessly increase the virtual disks of virtual machines that are configured for replication, without triggering an initial full synchronization.

After you increase the virtual disk on the source site, the virtual disk on the target site automatically resizes and the ongoing replication enters Resizing disk state, until the task completes.

Note: After you resize the virtual disk, vSphere Replication clears all available multiple points in time.

To use this feature, you need vSphere 7.0 on the source site and vSphere 6.5 or later on the target site.

For more information about disk resizing, see Change the Virtual Disk Configuration in the VMware Host Client in the vSphere Product Documentation.
