Hello, I use A2 Hosting hosting, and there is the Elgg installer, installation by just one click. when I get new updates, can I make them for this installer? I will have some problem !?
Upgrade instructions are available at http://learn.elgg.org/en/1.12/admin/upgrading.html and http://learn.elgg.org/en/stable/admin/upgrading.html.
As opposed to what @Jerome says I would suggest to upgrade from 1.8 to 1.12 in steps with only one minor version at a time, i.e. from current 1.8 to latest 1.9, to latest 1.10 etc., until 1.12. From 1.12 you can then really directly upgrade to the latest 2.3 and then to 3.0.
The reason for not directly upgrading from 1.8 to 1.12 is that - if I remember correctly - there's one upgrade script either in 1.10 or 1.11 that might result in the upgrade getting stuck when leaving out one of the minor Elgg versions in between.
The heaviest upgrade is the one from 1.8 to 1.9 (time-wise) as the data directory structure changes and also comments are migrated from annotations to entities in the database. The following upgrade steps up to 1.12 and even to 2.3 will go faster by comparision. The upgrade 2.3 to 3.0 then might take longer again.
What you also need to keep in mind is that you would need compatible versions of all 3rd party plugins that will work on the Elgg version you upgrade to. Depending on which 3rd party plugins are used this might be a bit of a problem as already Elgg 1.9 required some re-write of a lot of plugins. Then also Elgg 2 and also Elgg 3 are likely requires yet another rewrite of the plugins' code. Best would be to test plugin compatibility on a test installation before upgrading the production site.
Thank you iionly for your instructions.
