- We have a set of Informix-4GL applications which use a number of
- databases in a partition (Informix-ONLINE), for which we need to make
- a new release. As part of the next version we have:
-
- 1. Introduced some new databases.
- 2. Added some tables to existing databases.
- 3. Added some fields to existing tables.
- 4. Removed some fields from existing tables.
-
- This is all in addition to the code changes which operate on the
- databases.
-
- I need to come up with a procedure or set of tools, which can help
- automate the conversion/upgrade of the database(s) from one version
- (old) to the next (new). Are there any tools, or recommendations,
- from anyone that may have done this before?
-
- I am in the initial research stages, so I am looking at different
- alternatives. One suggestion has been to do a dbschema of the old
- database(s) and new database(s), and use the differences to
- build a set of isql commands to apply the changes to the old database.
