Following your instructions, I have a J2.5 installation with 1.9 version of your software.
I am moving to J3 so decided to first upgrade 1.9 to 2.5.
Followed the directions, uninstalled old, installed new without touching the database.
Now none of the download links work because the old download IDs appear to no longer be valid, and upon looking at the system it has given them all new download ids.
is this what is meant to happen, because if so then its a bit crap,
