Cleanup projects

["Davey ,Mr Paul" <p.davey@xxxxxxxxxx>]

Dear Professionals

This is rather a broad question, and perhaps this isn't the wisest time of
year to be asking it, but -

does anyone have a documented history, or is anyone at least able to direct
me to one, of major retrospective cleanup projects?
More specifically, of large-scale exercises involving evaluating name,
subject, etc. headings, of deciding on authoritative forms and merging or
creating cross-references.
 
This would in theory involve going right through a database from beginning
to end, but I wonder whether just starting at the beginning of the alphabet
and ploughing on through, is wise or feasible. Particularly if a costed
project is entailed and the purse containing the funding is not a bottomless
one. 
Perhaps, if one can prove that a project has started well and is proceeding
efficiently and yielding good results, one could go to management and ask
for an extension to funding. But perhaps it might be wisest to have a good
idea before the outset, how to prioritize.

I am cross-posting this message (hope that's okay)  as it is particularly
the post-migration period to Innopac that is of interest to me. But any
advice would be very welcome, especially if backed up by a diary of actual
experience. 
What went wrong would be as useful to know about as what went right.
