    Does not work.
    the Text is: Maximum upload file size: Unlimited

    but if you try to uploade the pop up comes up

    The file that you are trying to import is over the maximum upload file size limit of 512MB.
    You can remove this restriction by purchasing our Unlimited Extension.

    1. Muthali Ganesh

      After that you have to do the second part and edit the original extension ( the 2<<28 part)

      I’m having the same problem, after some research, I believe that the problem is that this is only working on version 6.77 and earlier, but now this is no longer available,

      The earliest version you can get is version 7.5 and up, if anyone knows where we can get the earlier version of the plugin, please share,

      For now, I think that you will need to buy it at https://servmask.com/products/unlimited-extension

      I also found it for a better price at https://www.nynology.com/downloads/all-in-one-wp-migration-nynology/

    Such solutions are no longer working in the latest releases of the plugin as they fixed such client side work arounds. The hard limitation for uploads in their latest versions is 512MB. Trust me on this one, I am Senior technical support at a hosting company. A work around in this case without purchasing the upgrade is to install an older version of the plugin such as:

    https://pluginarchive.com/wordpress/all-in-one-wp-migration/v/6-68

    and then editing the constants.php file and more specifically the line that states:

    define( ‘AI1WM_MAX_FILE_SIZE’, 536870912 );

    The number/restriction above is for 512MB so you could change it to any number you would like.

    Best of luck

    1. Muthali Ganesh

      Thanks for this information. I havent checked for the latest releases of the plugin. I will update the blog post shortly.

  3. Taskit

    Thanks I just used the extension and it worked like a dream with the latest version of the all in one plugin – but I only needed up to 512mb.

  4. Moxet Khan

    This method does’nt work anymore. It support 512MB only.

    1. Muthali Ganesh

      It works. Please follow the steps as mentioned in the blog

  5. Dennis

    Just go to this line:

    define( ‘AI1WM_MAX_FILE_SIZE’, 536870912 );

    add * 8

    So it looks like this:

    define( ‘AI1WM_MAX_FILE_SIZE’, 536870912 * 8 );

    Done, if you need more. Make 8 a larger multiple.

      Did you download the older version of the AIOWP plugin?

    This worked great until the most recent update. Now, there’s no way around the limit.

    hi guys!
    I have installed the latest version available and installed the plugin extension (https://import.wp-migration.com/), then in the constants.php file (public_html/wp-content/plugins/all-in-one-wp-migration/constants.php) change the variable to 30
    define (‘AI1WM_MAX_FILE_SIZE’, 2 << 30);
    and now I have a limit of 2GB;) I read in another place that worked like this in the new versions, installing that extension;) Try it.

  17. Gandhi

    In the latest version 7.7, Changing the max file size to ..2<<30 is not working. I am still getting the maximum upload file size is 40 MB. can you please guide?

    also I tired downloading the version 6.8 from the link provided by Angel Asenov. But this installing version 7.5.

      1. Abraham

        This worked for me. Just delete all last installations, install this and edit like the post says and it worked. No need the AIWP Import Plugin, just this. Thanks a lot!

    For those who do not work and have already installed ai1m, go to ftp and find the “ai1m backup” folder in the plugins folder and delete it. then install the plug-in in the version your colleagues write about and edit it. then it should work.

  19. Seun

    This no longer even with all versions of plugins. Today 2020-01-08

    I managed to change to several terabytes but each I try to upload my 8GB file, it peg me down to 512MB. So sad. I guess we gonna have to buy their product. Note that I tried this with latest version down to 6.65 version each time. Problem remains

  20. Thiyagesh

    Thank you, you saved me bunch of time.

    and the extensions file link is not working and also not needed I think.
    Editing constants.php worked great!

    If anyone could help me, I would REALLY appreciate it. So I downloaded the older version, went in and changed the code. When I imported it, it all came in. But when it came to setup the files, it would just hang and stay at 0%, After literally multiple hours of this, I stopped the process. It looks like my media and plugins were all imported. But there are no posts or pages. Any ideas? Did I do something wrong or is there an issue with Bluehost not letting me upload that many files? Thank you!

    1. Muthali Ganesh

      What is the size of the file you are trying to import?
