- before upgrade, you should backup SMVI repository, maybe you'll need to restore it manually (it contains the data what was backed up and when).
- VSC (Virtual Storage Console) is the integration point between NetApp and vSphere, it contains SMVI also, you can handle the whole thing within
this is from SMVI/VSC install doc about the repository folder:
"When you uninstall a previous version of SnapManager for Virtual Infrastructure (SMVI) prior to installing Virtual Storage Console, you have to save the backup metadata prior to migrating the backup metadata by copying the contents installed in the C:\Program Files\NetApp\SMVI\server \repository folder into the C:\Program Files\NetApp\Virtual Storage Console\smvi\server\repository folder.
After you finish copying the backup metadata, you must copy the contents of the credential file from the C:\Program Files\NetApp\SMVI\server\etc\cred folder into the C:\Program Files\NetApp\Virtual Storage Console\smvi\server\etc\cred folder."
