Also when I finish convert I must go through all my form and remove all code where I open my tables. This can be done in CA class, but after finishing conversion I mus remove that code from my class.

In BeforeOpenTables of the form I must have:
USE MyNatoveVFPTable1 ALIAS SomeAliasThatCAWillExpect1 IN 0
USE MyNatoveVFPTable2 ALIAS SomeAliasThatCAWillExpect2 IN 0
USE MyNatoveVFPTable3 ALIAS SomeAliasThatCAWillExpect3 IN 0
....
USE MyNatoveVFPTable20 ALIAS SomeAliasThatCAWillExpect20 IN 0
Of course all this could be done in CA class, but what if I have some CA that get data from many tables and uses many joins?
Are you sure that using USE .... ALIAS and after that base CA to that Alias is easier way?
