It kept saying no data engine could be found, even though the correct user, password and database name was entered … and it also kept recommending I use https rather than http (http is all I have)
I must have wasted 6 hours screwing around because of this “tool” … eventual problem was the database backup from the old host was too large for the new hosts phpMyAdmin importer. (I later split the upload into 3 parts)
After successfully uploading the database and getting the site running … for shits and giggles I tried the SMF tool again … yet the same fail results.
My lesson for the day … don’t always depend on a “tool” just because it’s called a ‘tool’.
