I had delayed migrating from Delicious to Pinboard I couldn’t find anything that conclusively said that the private status of a bookmark would be maintained in the transition. So I finally got around to testing it, it worked. Nice!
The entire export/import process took about a minute. Misc. credential changes, utility migration and/or changing the API URL in Pukka on 7 devices and a couple of home-grown scripts is taking longer than the extremely painless data migration.
