- If they are REALLY C-ISAM files then, unless I've missed my guess,
- all you need to know is the type of each data field in each data
- file. You also need to know the keys for each index.
-
- Now, in informix, create data tables of exactly the same type.
- Now once you've created the tables you login as user informix (or any
- other user with DBA privilage). Now create a default form for the
- table SYSTABLES. Now for each table you've created in SQL, change the
- dirpath field to point to your original data tables.
-
- So, you now have you're old data in you shiny new database.
-
- At this point I would suggest that you UNLOAD the bits of the data
- you need and LOAD it into you new apps.
-
- I hope this helps.
