Re: What does "DSN Migrate" in CSDK/Connect do?

Hello Richard, It is a rather unfortunate thing that the DSNs created using the older version of CSDK are not removed once CSDK is uninstalled. You are right in saying that users have to manually remove the DSN that has been created before uninstalling CSDK or I-Connect. As for the DSN migrate utility - it was designed only for migrating from Intersolv DSNs to Informix DSN. It could have been tailored to migrate Informix DSN also between versions, but apparently that did not happen and is not functional through DSN migrate. Going forward though the issue of orphaned DSNs has been taken care of. Starting with CSDK2.90, whenever the users uninstall CSDK, the associated DSNs that were created will also be removed so that this problem is not seen, Until then, I guess we are going to have to live this problem.
