Updating Ion Classic Windows 7 from 2.4.0

That means, your console looks like this?

Speaking from a software point of view updating directly is certainly possible.

There are some things to consider, some might be irrelevant depending on your venue and workflows.

• Starting with 3.2 you can't use the EDMX (ETC Net2) network protocol anymore. It was one of the legacy DMX-over-network protocols.
• Starting with 3.2 you can't use the aRFR/iRFR classic apps anymore. The newer (non-classic) apps aRFR/iRFR still work.
• Because all connected Eos devices need to use the same software version make sure also your backup console (if any) or designer client or classroom computers where they use the same software can also update

And of course when doing such a big step (2.4 is over 7 years old) it's important to allow for time to re-learn or re-train.

Yup, the console looks just like that.  Thank you for a great answer.  This was a very detailed and helpful answer.  

We have a show on stage now, so I would not even consider attempting to upgrade it until this show is finished.  We will have about a month off (only small dance shows on the weekend) before we get into the next one.  Figure that will be a good time to upgrade it.

There are no other EOS devices and no aRFR/iRFR, just a simple 1 universe system with a 96 rack and conventional fixtures hanging.  

Currently, we are rather basic in writing cue-to-cue shows and the fanciest that we get is timing changes between cues so I am not envisioning too much time to learn/re-learn.  No pallets, no groups...using it like a classic Express console to be honest.  We will be upgrading the fixtures with a couple dozen ETC ColorSource Pars this Spring, and hopefully a handful of S4 lekos being retrofit to LED.  With LED's coming in, the school's Lighting Designer (and I) are attending console training in Orlando in June just to make sure that we get everything out of it and to pass down to the next group that will be coming in.

Thanks again.  

Oh this makes me sort of sad. Using this console at such a basic level when it has so much power. The good news is you are getting new fixtures and having some formal training too. Might I suggest that you have a look at the workbooks and online videos before the training. I found it beneficial in my understanding of how things work. I wish you well in your learning journey. Remember one thing- Experts were beginners once.
