Does anyone have any experience updating EE with this big of a jump between versions? I need to update a huge website to 2.7.2 so that I can upgrade to PHP 5.3 on the hosting server. Being that it's such a big site and I don't really have any EE experience, I'm a bit gun shy. I've read and re-read the instructions for making a version update, and they do seem pretty straightforward. There aren't any add-ons that I need to worry about at least. Would trying this out on a local server first be an unnecessary hassle? Should I just make all my back ups and go for it?
I agree with the above, my method goes like this:
- Copy the site and database to a development environment, you can use your own computer running MAMP/WAMP, use a subdomain on the existing hosting account, or even an unused hosting account
- Take a backup of site and database, you can usually do this via the hosting control panel
- Upgrade EE1 addons/extensions/plugins to latest available
- Upgrade EE to 1.7.1 and check it all works as expected
- Take another backup
- Download latest EE2, and all the addons you need to replace via Devot-ee.com, extract files ready to upload
- Rename your /system /themes folders to /systemOLD and /themesOLD
- Upload the EE2 /system and /themes folders, and also the /images folder
- Upload addon files as per their instructions
- Run the EE2 installer and follow the on screen instructions
- When the installer is done login to the control panel and install addons
- Check your new EE2 site out, depending what you had on the old site you may need to adjust some template tags or tweak to get working again - often some addons require template tweaks.
