Just found this and it worked great on a site we were moving, so thank you! I've given a 5-star rating, and truly appreciate your work!
I did want to let you know about one quirk. We were on a Windows dev environment for this and found some cases of double-slashed that the script did not pickup. For example,
was not changed. The recently_edited value in wp_options seems to be the only core offender. We had one plugin do the same and have seen other plugins store like this as well.
We tried both C:\path\site and C:\\path\\site and had no luck with either, so I thought you'd like to know in case it caused issues for anyone else!
Thanks again for a great plugin,
