Flying club number change after renewal ??

Hi all,
I know there was a thread about this a while ago, cannot seem to find it.
Just been on the phone to VS asking a question about a flight. The very helpful agent informed me that my booking from my corp travel agent are coming thru with my old FC number that starts 00902xxxxxx and informs me that this has now changed to 00901xxxxx even tho my renewal cards for this year came through with the old number.
Is there a reason for this? does the change from a "2" to "1" mean I have slipped in the internal Au ranking :0 :0 or is this just an IT change??
Just really intrested as it means I have to go and update all my travel profiles.....
