reapply svn merge without undo - quick question

[Z W <mp...@gmail.com>]

Hi All

We use svn 1.6
We have a list of revision numbers listed in mergeinfo property.
Over the months, different folks perform svn merge such that there's a svn
commit failing but mergeinfo is still updated with that revision number on
mergeinfo property?
We don't know which revision number first failed the svn commit and yet
with updated mergeinfo.

We like to reapply all the revision numbers in the mergeinfo property.
What is the best way to guarantee all the revision numbers are merged
successfully from our trunk to a feature branch.

Can we simply issue command "svn merge" again on all those revision numbers
in mergeinfo ?

Thanks
