If you are a user or company making the transition from I-DEAS to NX via Teamcenter, there are a lot of hassles that you must deal with including data cleanup, buying new hardware, retraining, migrating data, software bugs, and paying higher license and annual maintenance costs.
That last part about licenses is what this blog is about.
Be aware of trading in your I-DEAS licenses for NX licenses until AFTER ALL OF YOUR I-DEAS DATA IS MIGRATED!
If you do not, you cannot upgrade you Teamcenter environment beyond the last I-DEAS version in your possession (DVD or previously downloaded) at the time your I-DEAS maintenance is dropped. I had this happen to me this earlier year.
The reason is that you will lose access to I-DEAS media when your I-DEAS licenses are gone since the SPLM software distribution (DVD or download) scheme follows what your active up-to-date SPLM license configuration shows. Yes, I know NX licensing can drive I-DEAS, but that is useless if you cannot upgrade I-DEAS to work with your migration tools.
As anyone that uses CMM to migrate data already knows, a currently supported I-DEAS version in Teamcenter is required as part of the CMM Process to repair data and workaround numerous CMM bugs. If you upgrade Teamcenter beyond a version that supports the version of I-DEAS you have, your migration process is derailed.
This forces you to either stay on your current version of Teamcenter until ALL of your required I-DEAS data is migrated to NX, or to no longer be able to properly migrate all of your required I-DEAS data to NX.
You have been warned!
