I have a customer who is wants to migrate his MSSQL database to PostgreSQL and we'll replace his application ASP with PHP. The issues should be limited as there are no stored procedures or triggers in MSSQL, just structure and data should be all that is needed to migrate. I have never migrated from MSSQL or to PostgreSQL, but have handled database migration in the past for other DB's. I know there is mssql2pgsql script out there somewhere and I find lots of info on the subject. Of course, when we rebuild his application, some db structure will change, I was planning to do all the changes to structure after a successful migration of his current structure now w/o data. After the new application is done, then create a migration path for the data. Is that the best way to handle these types of migrations? The customer will want to continue working on the old system during the several months of development in the new. Any docs or other helpful info is welcome, just looking for some advise. Thanks in advance, -- Robert
