Comment 5 for bug 1408542

As described in my earlier comment, for 15.04 we need to write a database script that rewrites all the old smiley URLs to the new smiley URLs.

Unfortunately... this will probably be a rather intensive upgrade, because of all the places we have TinyMCE text fields! So we should make sure to test the upgrade on a large site.

If we can't make it run well on a large site... it might actually make sense to just keep two copies of the smiley icons. Even though that would be extremely hacky.
