Migration Wizard Problem

Post by John Bell » Sat 01 Jun 2013 21:16

Using Delphi XE3 and MyDAC 7.6.12. Trying to convert a project with about 100 infopower tables in the datamodule. Wizard says it is successful but tables are missing and there are some odd error msgs when i open the datamodule. Are there some limits for the wizard i am not aware of. Btw the odd error msgs and missing tables are consistent between attempts. Thanks

Hello.

Migration Wizard replaces BDE/Infopower components with MyDAC ones. But note that
Migration Wizard simplifies routine operations only. If MyDAC components have not the same options as in Infopower components, you should replace these options manually.

OK, figured it out. the migration wizard gets very unhappy
when a table has IndexDefs (i had some tables which were
created on the fly with indexes). when the migration wizard
hits one of these, it stops processing tables on the form
and the new data module form is missing any tables afterwards
(but not the unit). additionally, the table with the indexdefs
has some errors with properties. in spite of this, the wizard
tells you it was successful...
