Thanks for your reply 
From what i have gathered and tested you can skip step 5+6 and not analyze them at all in serato
The reason for this is:
You use MIK for meta-data wihtin the id3 tags like key etc and cue points. Then put it into serator just to have an interface to EP. When first loading the library from serato into EP, EP will use id3 tags like key, bpm etc. Right now all your tracks have a “not-analyzed” status for EP or EPs own database respectively.
BUT when you start analyzing tracks within EP it will write waveform information, bpm, key etc in their own Database and USE THIS DATA exclusively! Hence it wont even show id3 tags within EP anymore but the ifnormation stored in the databse.
Do use id3 tag information again you can then “re-import track information”.
What EP cannot and wont do at all is using MIK or serato waveform, bpm!
So here is what i have done and it worked so far:
- analyze tracks in MIK
- Add tracks to serato, no analyzation needed (Lite or pro doesnt matter) (dont get confused Lite only shows like 4 cue points but MIK added all it could find)
- Update serato library within EP and add tracks to EP Collection
- Analyze track in EP
- Re-import track information
If you see flaws or have even a smarter approach, please let me know
!!! If my understanding of EP workflows and processes is false, please let me know. I have this infomation from here, which seemed quite sophisticated: https://www.reddit.com/r/DenonPrime/comments/a5iade/full_explanation_how_beatgrids_bpms_and_keys_are/ !!!
