Step-by-step guide
- Make sure that the MM you're about to install is compatible with the corresponding DAM Center. It can be found here Compatibility Matrixes (Usually, the newest MM and DC match up).
- MANDATORY: backup
- Database
- Jobs database
- web sites
- Delete everything but the web.config (and maybe your favicon/appicon if you've changed it/them) in your MM site's folder.
- Copy the content of the new MM into the old one - if you did not have any favicon/appicon from the previous installation, then you can safely remove the .new from those.
- Compare the old and new web.config file - if there are anything in the new one that you think should be in the old one, then move it. If in doubt, ask someone who you believe would know this.
- Be totally certain that you hit the correct database in the next step. Double triple quadruple check. It's really easy to make a mistake here.
- You now have to use the MM update scripts. Use this guide to do this.
- Recycle the site (a lot of really weird things can happen in the MM if this isn't done).
- Try uploading and downloading videos, pictures, change metadata, publish and so on. If all works, the site should be up and running.
- If you have a custom CSS, you have to recompile the variables.less, and put in the new CSS.
