1. Download and install the legacy Evernote v.6.25.x.x. Evernote has removed it from their website but you can get it at FileHippo. Download this now - I downloaded 6.25.3.9348 and used it, but now it's gone from FileHippo... not sure why. https://filehippo.com/download_evernote/6.25.1.9091/ I installed on a separate computer, but probably you can run v10.x and v.6.25.x on the same one.
2. Follow the undocumented trick for downloading all notebooks at once. This will preserve tags as well. Archived here: https://archive.ph/XDnqN - scroll down to KoZz's comment posted on "Tuesday at 11:53 AM".
3. Then if you want to move to Obsidian, use YARLE but note the template that automatically loads doesn't work (it has spaces and breaks other rules). https://github.com/akosbalasko/yarle
4. Template block definitions here: https://github.com/akosbalasko/yarle/blob/master/Templates.m... FWIW, I used this as my template (paste in the "Set Template" window for YARLE):
{content-block}{content}{end-content-block}
{tags-block}
Tag(s): {tags}
{end-tags-block}
