Upgrade 8.3

I am running the following query

update tempportfwdconnectiona set srcid=interface.objectid from
interface where tempportfwdconnectiona.hostid=interface.host and
tempportfwdconnectiona.spantreeport=interface.stpport

For application reasons the spantreeport in one table is a text field
and an integer in the other.

I am getting a cast error when I run this query which did work 8.2x, I
can't make both fields the same type is there any work around any body
can suggest.

I tried creating  a cast but the interface function text_int no longer
exists.
