"Bobby Gallagher" | Hi
This may have been answered before but I cannot find the answer I have both V3 and V4 of DBISAM and also Elevate DB. All of my applications are written for DBISAM V3 and we have been hoping to move straight to Elevate DB but don't have the time just now to do that. Would we benifit in the short term by moving to DBISAM V4 - I think that this should be an easy and quick upgrade. Just wondering what the advantages in doing that would be Regards Bobby |

With that in mind, and the fact that you plan on moving to ElevateDB anyways, I would wait and just make the switch when you're ready. Also, in case you didn't know, we can provide assistance with the conversion process to ElevateDB. Just contact me via email if you're interested. -- Tim Young Elevate Software www.elevatesoft.com |

Raul | We faced the same dilemma and it really depends on your code-base, short-term vs long-term requirements and time constraints. Based on my opinion (some sample coding projects with ElevateDB, reading manual and of course this newsgroup) the switch to ElevateBD is fairly major one in learning the product and also how you do things differently now. It's definitely the modern solution but will likely result in some short-term pain in getting everything re-written from DBISAM and working again. In our case we could not afford the time required to build own EDB knowledge and change all the code. So we went with DBISAM4 - we had most of the DB code in a couple of centralized units and migration was actually quite painless. Definitely read the differences document and test, test, test. We do still plan to move to EDB eventually but for now DBISAM4 provides a supported DB and we can maybe even wait for EDB Enterprise Just my $0.02 Raul |
