I am advising all of my clients not to update to 7.6.200 unless absolutely necessary. At this point that would include payroll users and a couple of other situations where a bug in 7.6.100a was addressed in 7.6.200.
On Macola ES, the data conversion is almost non-existent. If you can live with your vendors, customers, items, bills of materials, etc converted, then go for it. There is no conversion of Open POs, Open SOs, Open Shop or POP Orders, Open AP or AR, etc.
The accounting side of Macola ES is completely different and it is like learning a new product altogether. There is nothing you have learned about Progression that will help you at all in Macola ES on the accounting side.
On the distribution and manufacturing side, this is all very mature code and works very well.
Also in regards to ES accounting, be prepared to lose your F9 spreadsheets, any crystal reports that run on the accounting modules' files, as well as any screen designer or flexibility in those modules.
I wish the situation with ES was prettier, but it isn't. Maybe next year.
