What is your domain authority, age and indexed page number?

If you've come to the point where you've tried every possible e.g. cleared all crawl errors, disavowed and removed 7/10 links on the spam score link scale in OSE. Remove pages that Google may perceive as invaluable. Then and only then would I go to a completely new domain.

I wouldn't use any content from the previous site either as your original site would most likely be given credit for the original source since it's in Google's index already.

As you can tell it would be a last resort for me to move domains unless I had very few indexed pages / valuable inbound links and a low domain authority I could easily build up again.

Are you moving domains just because you've been hit with an algorithmic or manual action?

I'd personally try and solve the penalties before I'd make the decision to move to a new domain. If you don't want to solve the penalisation issues on your current site and move directly to a new one I'd try and distance myself from the old domain and establish no connection between the two sites.

If you feel your old domain has a high authority and you desperately want to keep the value you have built up then it's quite simple. You need to solve those penalisation issues. Work with the Google Manual action team to disavow spammy or illegitimate links. Focus on only keeping unique and engaging content on your site and adhere to Google Panda's solution criteria - duplicate content, titles, descriptions etc. Use Screaming Frog or Moz Pro to detect these issues.

Focus on helping the user while not breaking Google terms and conditions and you'll be fine.

One last note. A client of mine was hit with a manual action and I believe algorithmic penalisation. His site was able to recover in three months with a lot of work. The back and forth between Google's Manual Action team was the most time consuming.
