it's possible to use Adobe Acrobat DC 2015 with Adobe Livecycle ES4 PDF generator to convert documents on server?
According this official document  , it's not supported.
Thank you for fast response.
LiveCycle is replaced by AEM. LiveCycle ES4 is out of support, so no testing of newer apps will be done.
This is not what I asked, I know ES4 is EOL. I asked about possibility to use Acrobat DC 2015 together with ES4.
Like I said, no testing will be done and no document updated. But you are free to try it.
The official documentation has been created before Acrobat DC 2015 has been released. It's likely that LiveCycle ES4 PDF Generator will work together with Acrobat DC 2015. But, you'll have to try it yourself.
Btw. the LiveCycle forums are here: https://experienceleaguecommunities.adobe.com/t5/Adobe-LiveCycle/ct-p/adobe-livecycle-community
