For the tables, you can use third-party products (I think SDT will do that), or create your own solution:
Make all structural changes in an empty copy of the database. At the client site, copy this empty structure to a temporary location, and do an APPEND FROM for each table.
If there are parent-child relations (RI), copy parent tables before you copy child tables (use adbobjects("relation") to get the list of relations - you can ignore the relation if the third character in "ri" column isn't "R").
