2.10 SE -> 6.0 problems?

We are currently running various small SE databases on Unisys 5000 platforms in either 2.10.03G or 4.00.UEX. Most use some 4GL, and of course SQL. There are some fairly intricate select statements in reports, and we did have problems upgrading some to 4.0 with VEEEEERy slow performance which have mostly been resolved, with the list's help I might add! Now we will be upgrading hardware to HP 9000/877 and running some version of 6.0 SE and SQL and 4GL as appropriate. Are there coding changes to forms and reports and queries? Rules change? Performance problems/tuning to watch out for? Any helpful hints or warnings appreciated. If mail to me fails, try sending it c/o rmy.emory.edu.
