Re-sizing VMDK

Last Modified: 2016-02-29
How safe is to re-size over provisioned VMDK, specially the disk involving Exchange database partition. On my environment vmdk is carved out of netapps ISCSI lun. But my exchange is over provisioned with 1 TB when the database file is only using 300 gb.
I have primary Exchange virtual server hosted on ESX and secondary physical server as DAG /HA member member. I wanted to reduce size of disk to match physical DAG member 830 GB. Would shrinking cause issue with DAG or replication or database?
As Vmware article it sounds safe but I dont know how exchange DB and log on DAG going react to that change.
