refractoring tools or workflows?

[Tim Michelsen]

Hello,
due to a fundamental change of the underlying modules of my own code
(switch from one basic functionality module that got discontinued to the
successor), I need to refractor.

Are there any tools or special suggested work-flows in the bazaar
ecosystem that support the coder in this work?

Things like:
* rename old file as referece to filename_old
* register for which files the task is completed

Or is this far beyond the scope of a VCS?

Thanks in advance for your suggestions.

Kidn regards,
Timmie
