SVN: Must be ancestrally related. Tortoisesvn skips recording mergeinfo. Svn mergeinfo - E195016: “must be ancestrally related”. Although there are several similar questions here (e.g., SVN - Reintegration Merge error: 'must be ancestrally related') and on the Web, I wasn't able to figure out why svn mergeinfo <file> c.

The from/to date selectors are only for filtering what's already loaded.
If you want to use dates to fetch the log, use the 'show all' button
(press on the arrow, then choose 'revision range' from the menu and
enter the dates in the svn format).

Sure, you've replaced the trunk. The dev branch you originally created
is ancestrally related to the original trunk, not the new one you
created. Use the merge dialog and check the box 'ignore ancestry' on the
last page of the merge wizard.
