Converting to Joomla - will we lose ranking?

[databoroughseo]

Our Dreamweaver/manually coded website is becoming unwieldy at 100+ pages and is now being translated into four other languages, so clearly we need to move to a CMS.

Given that some of us have a little experience with Joomla, that's what we're considering.

My question:  with Joomla, or probably most other CMSs, I am assuming our url's will change.  Surely that will impact our google ranking, plus external links and so on.

What can we do about this?
