I have an old, half-done application in D5 using DBISAM 3.x that I need to complete QUICKLY.  The database part is rather basic and not a
significant issue except transition from DBISAM 3.x to 4.x

I want to complete application using Delphi RAD Studio 2007 and DBISAM 4.x (I have a registered copY of 3.x but not 4.x yet). I have ElevateDB
but don't have time to change/redesign DB backend - may be later. Actually, I wanted to move to ElevateDB but got stuck with Error #100, see
my post in ElevateDB General forum posted on 5/31/09. No resolution yet.).

I have been reading newsgroup and understand I will need to "UpdateTable" for DBISAM 4.x and deal with double-quote vs single quote issues.

Questions:
1.  If I remove DBISAM 3.x and install DBISAM 4.x,  will the DBISAM components on datamodule (Session, database, DBISAMTable,
DBISAMQuery, etc) still work ** OR **  do I need to replace these with compoenents supplied with DBISAM 4.x. (Data module has numerous
tables and quesries - it will be a real pain to manually replace them all).

2. Is there a "guide" or write-up for "Migration" and to avoid time-wasting gotchas one would expect during migration process. (There are many
scattered "pearls" in newsgroups - I am looking for a concise edition )

Thanks

JayM

Its a long time ago but the only issues I remember were the sql ones - mainly single vs double quotes.

The components from v3 to v4 keep the same names so it should be a simple matter of recompile. You might have to open the datamodule put a space in the .pas delete it to force an update for any new / missing properties but that should be it.

Mind you my memory is fading with age .......

There is an entry in the Elevate website with detail instructions.

Roy - Thank you. My main concern was re: DBISAM components on Data module that you answered.

Robert - I searched news groups - nothing significant (may be I need better search words). I have not looked into product manual - I am sure
there is something on "migration" there. Thanks for replying.

All: If anyone has a link to article/help on migration from DBISAM 3.x to 4.x - that will be greatly appreciated.
