So the way you are doing it will automatically work if you have 0 extensions. Right now it is very easy to upgrade if you have no extensions. I guarantee it has to do with a 3rd party extension that is not compatible. Would not know what to tell you without knowing what you have installed that is making it crash.

Also another thing you have to look at is the server disk space. If you don't have enough space you will not get a good update. I know it sounds simple but so many people have that issue including myself when I have forgotten to check.

Theme and extensions can be issue

I try to update fresh joomla 3.10 to j4 and crashes... best options is to manual transfer data from j3 to j4.

I agree with him.

same problem here, try to disable plugins and extensions

Before to upgrade to J4 your site need to be updated to the latest J3.10 version and make sure did your extensions are compatible with J4.
If there are some extensions which are not compatible with j4 your website will crash.

a lot off addons may not work, I had the same problems

 

[artweb]

Right, it is because in J4 the predefined Joomla php classes are different than the J3 predefined Joomla php classes.

is there any good solution please let me know

If it's a small crash, go to PHPMyAdmin, try disabling extensions one by one, untill your backend and front end reappear. In some 30% of crushes it works. Tested on some 20-30 upgraded websites.

You need to check every extension's compatibility with J4, especially the templates.. If they are not Core templates/extensions, you need to check them.
