if all client libs were the same, then maybe not but if there is a total
mismatch of client libs and an old app is using an old client lib with a
different connection string to the new apps/client libs, then there is a
good chance of corruption.
e.g. IB6 client with a local connection string on the local box Vs FB1.5
client lib with a TCP connection string...
