Theme:: Update from WP 3.9 to 4.9

To cut a long long story short, I am responsible for upgrading a corporate website that has not been updated for almost 4 years, besides publishing new articles. Back when I began here I was informed that this will be a top issue this year and that they can't upgrade it without loosing the entire base (I haven't tried it yet, but when they click on the automatic upgrade, there's a message that all the information in the base will be gone or something).

So when I suggested saving, refreshing, and simply re-importing the contributions, they said no, and that they'd rather just drop it and keep it as it is if it is. Actual release on the website is 3.9. I' ve been reading that if I upgrade in steps by hand, it should be okay, but this is a serious undertaking and a big concern for the business.

It was my intention to upgrade for each new full release, so: Refresh to 4.0 > 4.1 > 4.2 > 4.3 > 4.3 > 4.4 > 4.5 > 4.6 > 4.7 > 4.8 and then try the automatic refresh again.

Updating from WordPress 3.1 to WordPress 4.x

But before we go too deeply into the detail of how we have successfully updated the site, it justifies saying the following: Installation of a FRESH, NEW WordPress release (3.9.1 from this time) - This requires that you either have another hosted WordPress site (other than the actual manufacturing site) OR that you can have the new WordPress entity installed in a subfolder (i.e. /new) below the actual manufacturing site.

As long as you can build a second WordPress base (which is not the latest one) in your MySQL base. Sign in to the WordPress Admin Dashboard of the NEW WordPress page - This allows you to do a few house-keeping elements, such as erasing idle topics like TwentyFourteen & TwentyThirteen (I myself only keep an additional topic in case of bug fixing and favor the good old TwentyTwelve standard), removal or modification of the "uncategorized" mail categories, removal of non-relevant plugins and example posts/pages.

Uploading and activating plug-ins from WordPress 3. 1 - When you display the standard plug-ins that have been included in your new WordPress 3.9. Next is to go through and enable EVERY single PLUG. Writes the necessary records for each plug-in into your new WordPress 3.9.

Make sure that you run each one individually so that you can track any problems that occur and a complete reinstallation of the plug-in is required. lf so, refresh each plug-in. Homepage and Blog Page Settings - This is done by selecting Settings - Read in WP Administrator Dashboard.

Look at the way it is adjusted in the older WordPress 3.1 page if necessary. All posts and pages from the old page - Log in to the WP Administration dashboard of the old WordPress 3.1 and click Tools - Import. Click on the All Contents item and then on the Download Exportfile icon.

As a result, the content of posts and pages is stored in an HTML format. Now go to the WP Administration dashboard of the new website and click on Tools - Importieren and click on the WordPress button at the end of the listing (see Figure 6 below).

As soon as the Importers plug-in is in place, you will need to choose the appropriate filename you used to create the filename in the 6th steps above. Then click the Choose Files icon and find the . exml on your computer, then click the Upload and Imports Files icon (see Figure 8 below)>> see the Importscreen.

First, choose (or create) the name of the writer you want to associate with each of the recently added articles. Choose here and then activate the checkbox for downloading and importing attached files. Although you may not have associated attached files with postings, this is a good way to make sure that different types of contents are included.

Click on the Send icon (see Figure 9 below). Manual re-creation of the page menus - In order for your page menus to function again, you must click on Appearance menus in the new WP Administration Dashboard. There is one on the old page's main page and one on the new page's main page.

That makes it much simpler to rebuild the individual menus. We only had 5 major menus in our particular case, so it was pretty simple and fast. With your 2 screens (or tabs) open for the different WP Administrators mash-boards of each site (old and new), you can get into Appearance Widget and start creating each of the needed Widgets and assign them to their particular area within the site templates.
