I have three websites that are using outdated versions of Wordpress that need to be updated to current version. The webhost complains that the websites are causing too much load on the server.
The update must include a working install of the wp-super-cache plugin.
Two of the sites have tubepress installed to run the video gallery. This must still function after the update (as well as any other aspects of the website of course). If tubepress does not behave well with all the updates then an alternate video gallery plugin must be used.
This must be a seamless update and not damage the website for any extended period as one has very high traffic.
