batch-rename

in a directory with multiple sub directories I need to change filenames that have the "_" character to a another character "."

example

Current filename: ABC12345_DEF Change to filename: ABC12345.DEF

I need to do this recursively through a directory tree.

the last three characters of the filename are not always the same.

using rename wildcards on either side of the "_" or "." doesn't work (plus I need to do this through several directories)
