DNAC swim does all the checks and give you error if any and guide you too.
DNAC dashboard give you what version of code running - when you select golden image it will upgrade to that version (before upgrade as i mentioned it will do all the check before proceedings).
If you upgrading from DNAC - you need to upload image to DNAC repository, have you read the document provided for SWIM Upgrade.
DNAC automatically sync once switch added to DNAC, if you like you can re-sync again before if you like to do so ?

DNA version is 1.3.3.9
this version have many bugs, rather i use this DNAC i manually upgrade the switch.
the code you upgrae 17.9.X is latest - i expect DNAC should be 2.3.X or later.
