 In this video, I will show you how easy it is to migrate from oncloud 10 to next cloud 12. As you see, I have oncloud 10 running here, including a couple of applications like contacts and calendar. I also installed the audio player app, but for some reason it does not show up. So, let's start the migration. So you simply go into the folder where oncloud is installed and you copy paste the commands to download the index.php file, which is the migrator, and then you move it into the update folder. You see it gets named index.php.1 because there is already an index.php file. And then you simply visit it into the browser. So you go to updater slash index.php and there is the migrator. It correctly detects we're running oncloud 10.0.0 and we can migrate to next cloud 12. So let's get going. The system is checked. Put in maintenance mode. Backup is made. The files are downloaded. The integrity is verified. The files are extracted and very quickly we are ready to continue. Now we can let the web-based updater do its thing, but I'm going to use a command line tool to show how that works. So the system is in maintenance mode and we run the upgrades. Well, that's easy and quick because that's done now. So now we need to turn off maintenance mode. I always forget the exact command. Maintenance semicolon mode. Now colon mode and minus minus off. Now let's check in our next cloud instance. We've upgraded to a much faster and more secure next cloud. Just to refresh. And here we are. You see there's a problem with the code integrity check. Next cloud checks if all the files are secure. So you see a number of files that have filled the integrity check. This is the auto player, the calendar, the context, and the personalized apps. So these certificates are not trusted. They're still own cloud certificates. They're not next cloud certificates. So you wonder what can we do about this? Well, we're going to go back to the app store. So we simply need to replace them with versions from next cloud. Well, you see there are newer versions available, so that is very easy. The audio player doesn't have a newer version available, so we simply remove this one. So we re-enable the calendar, context, and the personalized apps. You see them appear on the top. And then we go and install the audio player app. Ooh, and there's video calls. Let's install that too. So now these apps are back. So we go back to the integrity check and let it do a re-scan. And now you will see that all files pass the check. Note that you will not have to reinstall or re-enable apps when you do an update from next cloud, because in next cloud 12 we automatically re-enable apps that were enabled before you run an update. Thank you for watching.
