Review Comment:
So, I will change the syntax like:
```
ALTER TABLE prod.db.sample REPLACE BRANCH audit-branch
AS OF SYSTEM_VERSION 4567 RETAIN 60 DAYS
```
and for branch
```
ALTER TABLE prod.db.sample REPLACE BRANCH audit-branch
AS OF BRANCH branch-2 RETAIN 60 DAYS
```
I think we are not using version but system_version everywhere.
