My X3 Producer includes things that Sonar Professional lacks so I’m wondering if I will lose any of the below if I make the switch?

Dimension Pro 1.5
Rapture 1.22
XLN Addictive Drums 2 (3 multi packs versus 1)
Melodyne Essential 2

Sonar Professional comes with Melodyne Essential 4 but do I get to keep the Essential 2 license as well?
I am thinking of upgrading Essential 2 to Editor 4 so I could find a new home for Essential 4 if the licenses are treated as separate.
I don’t want to pay the much higher price in the long term to move to Platinum.

Cakewalk provides one license for Melodyne per SONAR license. Upgrades do not qualify for an additional Melodyne license. Whether you choose to upgrade from Melodyne 2 Essential to Melodyne 4 Essential is your call. Celemony provides a free upgrade to Melodyne 4 Essential for all Melodyne users. To upgrade you will have to surrender your Melodyne 2 license.
 
All the other plug-ins mentioned in the OP will work in SONAR Professional.
 

Enjoy!!!!

That seemed to be the obvious way it would work regrading the license but figured I'd check.
Are you implying that if I stay with X3 Producer that I am also eligible for a free upgrade to Melodyne 4 Essential or as I imagined only if I upgrade to Sonar Professional?
I figured it was a paid for upgrade but can't seem to find an upgrade price for Melodyne 4 Essential!
 
Good to hear that the other content will still work which makes sense but again I find it best not to assume things.
Thanks for the replies.

As an owner of Melodyne 2 Essential, Celemony provides the upgrade to Meldyne 4 Essential at no charge. To see the upgrade policy, click the "melodyne essential 1 and 2" button in the "Updrages and upgrades" section here  
 
You will lose some features such as the Quad Curve EQ flyout and powr dither. Search the current help for "platinum only" to see the features not included with Professional.

Thanks, that is good to know if I decide to stick with X3 Producer and I am eligible according to their conditions: 
 
"All users who registered their Melodyne after Nov 1, 2015, get the update to Version 4 free of charge."
 
As for platinum it seems a bridge too far for now but if I get on the new platform who knows down the line.

Melodyne upgrades are half off now, so if you want to upgrade to Editor, now would ne a good time.

Thanks, that is why I am considering it now and was asking about the license situation.
