I'm trying to update my development site on MAMP from Craft 2 to 3. I've installed Composer and tried both upgrade methods (keeping the current directory structure & using the new structure). But with both options, I keep getting shown the install craft screen instead of the update screen. Which is not what I want to do.
I've added my info to the .env file, but the only way I can seem to get the update screen is by using my old db.php file from craft 2. But then that means that I can use the .env file.
If I then go to complete the update, I tells me that craft can't do a database backup. If I then continue the update to craft 3, when I log in I'm shown the following dependency error:
The auto-generated validation key stored at /Applications/MAMP/htdocs/lorindafontainefarris/craft3/storage/runtime/validation.key has been deprecated. Copy its value to the “securityKey” config setting in config/general.php.
I don't see a validation key to copy, but I already have one that was created for the .env file. Its just not being used because I've used the old db.php file from my craft 2 build. I'm assuming that I shouldn't have to use my old db.php file to get the update to work.
So can anyone shed some light on why I keep seeing the Install screen when I go to update my craft2 project?
Thanks in advance,
