SVN merge without mergeinfo

If you are about to merge a branch back into trunk and experience the following error, you are using svn 1.4 or your admin forgot to update your repository.

svn merge --reintegrate http://svn/calc/branches/my-calc-branch

Querying mergeinfo requires version 3 of the FSFS filesystem schema;

In this case you could use:

svn merge http://svn/calc/trunk@X http://svn/calc/branches/my-calc-branch


svn merge -r X:HEAD http://svn/calc/branches/my-calc-branch

where X is either the revision you created your branch from or the revision you last merged into your branch.
