Works fine as long as you have a SMALL site.

I have used this plugin for 3 websites without any problems whatsoever. Those sites generated migration files of 170Mb, 227Mb, and 243Mb. I just did one at 288Mb and it would not import. Imagine my horror.

IF YOU ARE ON DREAMHOST, here’s some tips to make this work. It took me 2 days and lots of tech support chats to ferret this out.

The maximum upload size, by default on DH, is 256Mb. You can tweak wpconfig and php.ini (called phprc on DH) and increase things, but you will continue to get the following error…

…mod_fcgid: HTTP request length 268443648 (so far) exceeds MaxRequestLen (268435456)…

There are TWO KEY THINGS in that error message. The first is the actual parameter cited (MaxRequestLen) – you have to get DH support to increase this because it is server-side and you don’t have access.

HERE IS THE SNEAKY SECRET: The other key thing in that error message is the name of the PHP module running: “mod_fcgid“. It means you are (properly) running the FAST CGI version of PHP (mine was 7.4). Because of the way that Fast CGI works, there can be a disconnect in communications between the PHP processor and the Apache server. I don’t understand the woo-woo, but that’s what happened.

Long story short, DOWN-SHIFT from Fast CGI to STANDARD CGI in the control panel for that domain with the same version family (e.g. 7.4 Fast CGI to 7.4 CGI). Nothing that DH support did for me on the server side worked until I did this. On the next import attempt, it worked and completed.

After you get your import done, back out all of your wpconfig, phprc, and your DH CGI settings so that the site is running with default parameters.

I will probably never use this plugin again because now DreamHost has their own migration tool and it is not subject to the upload size restriction. You can possibly chunk your upload with this tool, but if you attempt to upload from anywhere other than your PC (Google Drive, URL, Dropbox, etc.) they want 100 bucks for that addon. That killed it for me, that’s excessive.
