Remember that Sage will shortly STOP sending out updated Extended Solution bundles. This will be problematic for ANY customers still using ES on versions prior to 4.4 who also need to add another add-on that requires an updated ES version.
We ran into this with DSD’s IMFX utility which was certified for the latest 4.3 SU and the customer was on SU 14 with two legacy ES.
We also ran into this during payroll year end when Sage pushed out mandatory payroll updates (at least mandatory for any customer who wanted to compute the proper CT withholding) and it required a specific SU level to install. In those cases we were forced to quickly go to Sage and get an updated SU.
TIP: Any customer using Extended Solutions, not on 4.4 and not planning to move to the latest version of MAS soon – should ask Sage for the latest upgrade to their Extended Solutions. Sage is indicating that they will soon “remove the program” that generates these updates and the bundles will not be available.
