The nicest solution would be that your hosting provider would roll back 
the PHP update at least temporarily until you have finished the upgrade. 
I guess that won't happen.

I assume that you have access to the files with SSH/(S)FTP. If that is 
not the case, ask your provider for that.

You can still use the normal upgrade guide [1] and skip anything you 
can't do because the 4.5 backend doesn't work. Instead say a little 
prayer that most of your extensions were already compatible with 6.2 and 
that the reference index was already up-to-date.

The 6.2 Install Tool luckily has an option to test if installed 
extension will cause fatal errors in the backend and it gives you the 
opportunity to de-activate them.

Make really sure you have backups of the entire installation (both all 
the files and all database tables) so you can restore everything and try 
again (or hire someone to do the upgrade).
