There is a built in automatic upgrade feature in b2evolution 5.1 and above.
It is generally a good idea to try this before using a more complex form of upgrading. However, as always it is advise that you have made a backup of your site beforehand.
What if auto-upgrade fails and my whole blog is "Under maintenance" ?
The "under maintenance" message is displayed because of a temporary _maintenance.html file that can be easily deleted.
However, if the upgrade procedure left your blog in a half upgraded state, you will probably need to restore backups. Note that the auto-upgrade procedure starts with making backups (see the _backup folder on your site) and won’t change anything until the backups are complete. So everything should be fixable in a fairly easy way.
Hi all,
I did a clone my blog (DB) so I did an installation version 6.0. After I did an auto-upgrade-procedure (6.0 -> 6.1.2) and all worked fine!
So I ask. Is it secure auto-upgrade from 5.1.2 to 6.1.2? Thanks (and forgive my bad english!)
