Upgrade from 4.3.6 to latest version

[Betasom administrator]

Unfortunately our installation has not been upgraded since 2013, so we have 4.3.6 installed. We are not able to make the upgrade to latest version as the upgrade needs php 8, but 4.3.6 do not work with it (only up to 7.4).

How could we proceed for an upgrade? Is it possible to download intermediate versions and make an upgrade by steps or are there other solutions to try?

 

Thanks

You can upgrade directly. The best way to go about this imo is to first disable/uninstall all third party apps/themes as most likely they will need to be upgraded too to be compatible with php 8.x. Then make a full backup of the database and forum files. Upgrade php to version 8.1. and then proceed with upgrading the forum.

I read the title as 3.4.6 at first. I've recently done 2 upgrades from 3.4.6 and 3.4.9. 😅

 

IPS doesn't provide older versions for download, so you can only upgrade directly to 4.7.14.

The steps mentioned in the post above are all you need. However, remember that you can't use the automatic upgrade option in ACP in this particular instance because you need to change the PHP version.

The only option is to perform a manual upgrade. Here's a link to the guide: https://invisioncommunity.com/4guides/advanced-options/server-management/install-and-upgrade-r259/#manualupgrade
