Dear all,

We just realised that the 'template_view' is a new view introduced only on
Cloudstack database version 4.2. CloudStack 4.1.1 doesn't have this. It
seems that during my failed upgrade attempt last time, I did a restore of
the 4.1.1 database over the existing 4.2 database (instead of over an empty
database), causing some new views/tables introduced on 4.2 still exists on
my restored 4.1.1 database.

Anyone can advise how can I do a clean-up of the existing database so that
I can do a proper upgrade from 4.1.1 to 4.2? Other than template_view, any
other view/tables or column (on an existing table) I need to delete?

Looking forward to your reply, thank you.

Cheers.
