Re: Reverting from 11.X -> 10.X using onmode -....

Posted By: John Miller iii

In Response To: Re: Reverting from 11.X -> 10.X using onmode -.... (Michael Wiggins)

Michael:

It is not that it does not work for xC4. It is that at some point in time
while running
xC4, someone took advantage of a new feature which is only available in xC4
and
not in previous versions. While this might not have been by a direct
action, it can
be an indirect action.

Example: Someone ran update statistics on a table. That tables

was utilized in a stored procedure, which was later executed

by a users. That stored procedure is now out of date because

of the update stats, so it automatically re-compiles and
re-optimizes

itself which utilizes a new SQL feature to execute the queries
faster.

When doing any reversion it first check to make sure you are not using any
new
feature which are specific to the newer version (in your case xC5). The
reversion
founds some new feature that are specific to xC5. Before allowing you to
continue
you must manually remove the use of these new features. Once that is done
you
can re-run the reversion process using onmode -b.
