We have migrated our legacy historian several times using saveh50 and loadh50. It actually works pretty well.
The saveh50 utility unloads the Informix data and table structure to a series of sql scripts and files of ascii data. There is not a lot of interaction once the process starts. It takes quite a bit of time (hours) to unload the database depending on the machine and the amount of data. Be patient while it runs. Before running the loadh50 make sure you have allocated enough space to the informix raw partition. If I remember correctly the default is only 50 Meg. There is a helpful hint HH528 on expanding the raw partition and checking the size of your current partition.

Customer needs to make larger his historian, from 500 to 1000 points without loosing his preexisting configuration. Do the saveh50 and loadh50 utilities allow this? Step by step: -saveh50 -recommit with new historian size(same name) -loadh50 is this possible or is it enough?I've looked on Helpful hints, CARS, but i've not found documents about this. Thank you in advance.
