Upgrading VMFS3 Datastores to VMFS5

[Demuz]

Hi,

If I have a VMFS3 datastore with 1MB block size limiting max file size to 256GB and I upgrade this datastore to VMFS5, will it remove this limit?

[Cooldude09]

yes, it will grow automatically only after ui exceed 2 TB limit

Also you cannot modify the block size in VMFS5, it supported only 1MB
