What John said is generally true. However, back when I first moved from 32-bit to 64-bit, and "cut the cord" on 32-bit SONAR, I found a wrapper-type facility called DX Shell -- here's a link to a KVR post on it:
https://www.kvraudio.com/forum/viewtopic.php?t=177538 -- that allows wrapping 32-bit DirectX and DXi plugins (also MFX, though I never had any luck getting the ones of those I tried to work) for use in a 64-bit environment. They essentially become VST plug-ins after a one-time effort in wrapping them. The download link for DX Shell at that location still appears to work.
I had mixed results with this. Some plugins (e.g. DreamStation DXi, TimeWorks CompressorX and Equaliser, dB audioware's suite of dynamics processors) worked great, some didn't work at all, and some "sort of" worked but had issues such as with controls inside them. Here's a link to a Google Groups post where I discussed some of my results:
https://groups.google.com/d/msg/cakewalk.audio/SoP5iuw29vo/xiF61EhSbyMJ. To the best of my recollection, I did not try DR-008 (I think I'd already stopped using it some time before that).
This was back on 64-bit Windows 7, but, when I built a new system with Windows 10 (now running SONAR Platinum), I also used this solution to bring some of those plugins forward (including all the ones mentioned above) forward. The bigger problem I had on the new system was needing to reinstall some of those programs, where I couldn't get them to install properly on Windows 10. I know, for example, that the old versions of Waves RennMaxx I had fell by the wayside when I build my new system, and I'm pretty sure it related to the PACE/iLok stuff in the old software.
DX Shell might be worth a try if you have projects using DR-008. Might work.
