Transferring RW blog to Alloy and disqus comments

Hi Foundry pros,

Please can you advise. I’ve got a RW blog page with 12 years of worth of posts and a lot of great comments in disqus which is linked to the RW blog page. I’m increasingly frustrated by the limitations of the RW blog page and thinking of transferring to Alloy. Do you know if:

Its possible to preserve the existing URLS exactly if if set up tidy links? (Various posts are linked to from other sites?)
To add disqus to the Alloy posts?
If it is possible to add disqus, is there any way to preserve my existing comments or will these be lost when I tranfer the blogs into the new format?

Has anyone had experience of doing this?
Thanks and best wishes , james
