Hello ThePants999
Welcome to Communities.
I too have never heard of any such limitation - where perchance did you hear/read this?
This is generally a great (and current!) resource for such information:
Edit: for some reason it is preventing posting comment if I include resource link if you google vmware-product-guide 2019 you will find it.
Potentially your source was thinking of limitations of these licences for VSA <sniggers in HCI :smileygrin: >:
"If You obtain a license to VMware vSphere Storage Appliance for VMware vSphere Essentials Plus as a part of Your
license to VMware vSphere Essentials Plus, You may use VMware vSphere Storage Appliance for VMware vSphere
Essentials Plus only on a single Cluster."
Or multiple vCenter limitations:
"You cannot connect multiple instances of VMware vCenter Server to the same Single Sign On (SSO) federation."
Other than the above examples I can see no indication of such limitation and if there were it would be stated in the linked documentation.
If you want to be sure for sure though, consider calling our licensing team, if they inform of something not noted in the documentation then that would need amending.
Edit2: Had a look and seems was potentially a limitation in the past - not looked into documentation to corroborate though:
