Bulk External Link Change/Update Plugin for WordPress Blog

I've a WordPress blog having many posts having external links to certain domain,
example.com/pageA
example.com/pageB

I'm looking for plugin that can change the external domain from example.com to example2.com in all posts published.
It could be one-click change/update kinda.

does anyone knows about such plugin?

Why not just use htaccess for this ? do you really need plugin for that ?
