Converting from 2018 to IRIS 2024

Discussion

Hi Guys,

I'm new to IRIS and I'm converting from Ensemble 2018 to IRIS but not sure how to convert my cache.data file to IRIS.dat, I copied my cache.data to a new folder then went to IRIS management portal and created a new database and specified the directory to where my cache.data and saved and I thought that IRIS will automatically convert cache.dat to IRIS.dat but instead it created a new empty IRIS.dat, I guess I was wrong in my assumptions !?

also by leaving the New Volume Threshold size as zero is that mean that I always have only one IRIS.dat instead of having multiple files ?

Thanks

Way back some years I simple renamed CACHE.DAT to IRIS.DAT with IRIS stopped.
No guaranty this still works.

* don't forget all CSP content
* don't forget to run $SYSTEM.OBJ.Upgrade()
