I'm a solo hobbyist developer with some code hosted on Bitbucket. I use TortoiseHg client-side for managing my repo.
Back in 2013 I developed a feature on a branch but abandoned it before completion.
The default branch has seen many commits and structural improvements since that time.
Now I'm to a point where that abandoned branch's feature has become appealing again, and I'd like to resume working on it.
First, however, I'd like to bring it up to compliance with the existing site design.
I'm unclear on what the correct Mercurial step is for reviving this branch? It seems obvious that I don't want to Merge with Local... with local being the most recent default code. Update to... would pull the most recent commit from the old branch down to my computer, which wouldn't have any of the system-wide improvements made over the intervening years. So?
