Now we needed for support of other DB Engines, and now we have bought UniDAC. In parallel with SDAC UniDAC cant be installed, and I have started the Migration Wizard.
But at migration of property TMSQuery.Options. UniqueRecords did not migrate, and I should make huge work on manual removal of property from all dfm-files.

Also not migrated: TMSQuery.Options.NonBlocking, not all TMSQuery, TMSStoredProc migrated with invalid property TUniStoredProc.SQL.Strings, TMSConnection.ConnectionTimeout not migrated as SpecificOptions.ConnectionTimeOut, TCustomMSConnection and TCustomMSDataSet are not migrated, TMSMetaData.ObjectType is not migrated as TUniMetaData.MetaDataKind, TMSMetaData.DataBaseName is not migrated... This list is infinite!
Please, make possibility to install SDAC and UniDAC together, for support of the big old projects!
