I have been using Dokuwiki for the past 4 years, and it has served me well till now. However, no offline solution in mobile is a very critical limitation to use Dokuwiki as a personal knowlegement management (PKM) app.
I have decided to move on to Obsidian. However, Dokuwiki is a wiki tool I will look forward to.
I have created a python script which converts my Dokuwiki notes. You can find the python script at https://github.com/ReactiveMatter/dokuwiki-obsidian.
I hope it helps someone.
