I seem to remember doing this when we went through a migration to NFS from an older iSCSI datastore infrastructure in 4.x. It basically facilitated a physical migration for us. One thing to note here is it wasn't a "shared" instance and more of a cutover type scenario.
What are you trying to accomplish? what type of storage are you using?
Welcome to the Community,
basically a VMFS datastore can be shared by up to 64 hosts, no matter whether they are managed by vCenter Server or not. However, you some features (e.g. Storage I/O control) may not work properly with "mixed" access.

I have one VCenter 5.0 server that has a bunch of virtual machines that have access to a SAN where I have a floppy image resides. That floppy image is shared among the VM’s.
I have another VCenter 5.0 that also needs access to the same floppy image. This other VCenter has a virtual machine that is writing configuration information to the floppy drive and then the virtual machines on the other VCenter pick up those changes (I didn’t created the app’s on the VM’s, that’s just the way they work, but, I have to deal with it).
