How do I update from a previous RC to RC-4? This question will continue to come up again and again. And Paul has once again done an excellent job putting together instructions on how to update to RC-4. But alas, they will be missed or overlooked. So, here are the instructions in a nut shell.
Note: This does not apply to any other upgrades, i.e., 1.4.x to 2.0. If you have any questions, go read Paul's
instructions.
Okay, let's start back at the beginning. Make a backup of your database. While that is happening, you may want to reread the
instructions that Paul did up - he did put a lot of effort into them.
I wouldn't recommend a
copy over technique -
many files have changed (added/deleted) between the previous RC's and RC-4.
Make a copy of your current RC files and put them in a directory somewhere for backup purposes.
Upload all the files from RC-4 with the exception of config.php (you'll see in a moment), install.php and upgrade.php.
Copy the config.php from your old files (good thing you did that backup earlier) and upload to the RC-4 directory.
Right now, you should be able to go to your forums. You may not be able to read anything and the color scheme may appear blue - that's normal if you haven't applied the update.
Now run update_to_RC4.php. You may get a few errors. Read these errors and make sure nothing is out of the ordinary.
Remove update_to_RC4.php.
Go to site. Login. Have fun.
Now wasn't that simple?
Edit: This post has been updated to reflect the new upload of RC-4.
