Pre Pro Chanel, Sonar used to have its own EQ which was at some time upgraded to the Sonitus Eq for versions of Sonar that didn't have Pro Channel.
This meant that for backward compatibility, the Sonitus Eq was used instead of the default and lesser capable standard Sonar Eq.

Reminds me of walking in to a DR's office and you notice they are still running Windows XP

And that's probably not by accident. It's not like they're averse to upgrades, at least not for medical equipment (or the cars they drive, or the golf clubs they own). But a dentist doesn't have to worry that the drill he used yesterday might not work today because gremlins snuck in during the night and swapped it for a new model.

I had an issue when opening Sonar X1 sessions on Sonar Platinum... The output of individual tracks were playing out at a lower volume than they should be. There were no Offset mode volumes. Once I turned the input Gain knobs off 0dB and back again, it reset the tracks to their correct volume and stayed that way after re saving the new project. Must be a bug.

The reason the big network users like where I work at a huge Health Athourity with probably 10,000 computers with very personal and confidential info stashed stay with older OS systems is the techs are 99.8% in control, not Micro soft. My wife ran a Dentist office for 30 years and was one of the first to use specialised software to manage the the charting, scheduling and billing. They stayed XP for at least 3 years into W7. It took the software developer a while to write all that new code for W7.  They are still W7 because the software only runs on that. Upgrades cost $$$$$$$$ and even Dentists can't blow all thier money on software.  
The healthcare Authorities have the same issue and just like us it's compatibility with hardware, software and specialised drivers for medical equipment.   
So when you saw the Doctors office running XP , it was not because they are lazy and out of date. It is because OS upgrades are not possible unless 100's of other pieces of equipment, software and ?? are also updated. 
 
W10 was a move towards the idiots in the mass market consumer world of Facebook,useless apps and cell phones, it was never designed for business. And for me, not for DAW's either....
 
 

I'll tell you the issues I've had, bats...and you can just keep these in your back pocket.
 
For starters, definitely put Sonar 6 on the new machine. It's such a small fingerprint, it's worth it to have just in case, like the others have mentioned to you. Plus, you will have all those old faithful plugs that you will NOT have on the newer Sonar.
 
Next, go into plugin manager in Sonar 6 and export all your custom plugin saves you may have. You will be able to easily import them all back in and have them if you need them. I have several "good starting point" plug saves that I use religiously. I'd really miss them if they weren't there. You can do this if you use DX plugs as well. You'll see an export option in plug manager and an option that allows you to see what saves are literally in that plug menu. It's pretty cool.
 
If you are an embedded, per channel Sonitus user, you're pretty screwed. The pro channel change and backwards compatibility are a bit tricky and I hated that whole thing. Though there was probably no other way the baker's could have done this, it's always something that has bothered me. Clicking on the grid sometimes alters your settings in the Sonitus....you know how you double click to see the plug on the channel? That's what I'm talking about.
 
When you double click, it can alter the eq settings and you can't even see what you touched. Once you open the plug, if you didn't memorize the eq setting, you don't know what moved when you double clicked it. But you'll see the grid change so you know something changed. So any Sonitus eq stuff (the embedded Sonitus) will be a challenge. If you used Sonitus in the bins, you're fine.
 
Waves: I've had quite a few issues due to updating Waves and them changing either CLSID numbers, (each plugin has a unique number like a license plate) or when I used the Sonar option "hide related VST 2 plugins" due to the implementation of VST 3. So you may be redoing a few things until you figure everything out. Other times, I've had no issues at all.
 
Lastly, take notice to how your pan laws are set in Sonar 6. This has made quite a bit of difference for me with older projects. Currently, I have Sonar 8.5, X1, X2, X3 and Plat installed on my system. This way I can open old projects that were created in those versions if I really need to. But if you use the pan laws you had for Sonar 6, you'll have less of a chance things will be different. Then again, I believe Sonar has some new thing in it that knows what pan laws were used in an older project and may compensate or something. I know I read that somewhere, but do not know the full story there.
 
The main issue you will have is anything you do in this new version, will not work as well in the old version should you need to go back. If I can think of anything else, I'll let you know. Good luck with everything!

all good insights...
 
and danny, your suggestions are spot on for the way i run stuff...
i'll have to do a lot of note taking before i open up in newer version,
and just simply use new plugs for the ones that bugger up.
 
and pan laws, good point.

Yeah if you have any issues or whatever, let me know. I have a feeling you an I run the software very similar...like a big tape machine without all the bells and whistles, right? LOL! I was perfectly happy with Sonar 8.5. If they didn't come out with so many more innovative things that I found both useful and less time consuming, I'd still be on 8.5. So I can relate with you staying on 6 for so long. When something works with this stuff...man, you stick with it as long as you can.
 
I didn't do Windows 10 (which I may regret down the road) for free when I had the chance, but I'm done for if I have to sit around playing with drivers and software that won't work any longer. It's bad enough they get you for a new pc and a new operating system, then you need new software too and the learning curve and time spent is really insane. It makes you want to just buy a freaking reel to reel and get back to work! When you are used to getting your work done (whether it be you as an artist or in business) one of the most depressing things is to sit and tweak a computer to where the one you had before fired right up and worked the way it should.
 
I look at computers and software like a bios update...you don't do it unless you absolutely have to. A well-oiled machine is just that....a well-oiled machine. HOWEVER......
 
The new Sonar Platinum is an extraordinary piece of software. Once you learn where everything is and get used to it, you'll find your work flow will not only improve, but will get faster. Some things, you won't be down with because you will definitely need to change the way you think as well as the way you work. But once you get used to the things you HAVE to do, I think you'll be in much better shape. The good thing about you is...you don't need software or plugins to make you sound great. You got that part down. ;) It's learning all this stuff and sort of starting from scratch that will beat up on you at first. At least you have a few hundred brothers on here to help you out should you get stuck....so you're still in good shape. :)

yea, i've skipped a lot of upgrades for a very long period of time,
and am all the happier for it!!
 
but now, it's time to bite the bullet.
