All in One Migration Import Limit

Hello local community. I recently switched from Bluehost to Flywheel I created a backup with all in one backup file ( I have used this method a lot) to easily import/export sites, however now that I am trying to use local to bring back my old site to use a few things I have there (don’t need it all) it turns out that the backup file is too big and neither all-in-one (free version) or WP import allows me to do so. Before I pay $60 for a (basically) one-time use of all-in-one pro version I wanted to see if there’s a way around this. The file I have is .wpress. Many thanks in advance for any tips



Hi Maria-Ines,

Can you provide the error that you’re seeing when importing the large backup?

A screenshot would be ideal! :smiley:

@clay Actually I did have also the similar problem. A large multi-site import does not work. My database dump is around 700MB. I tried everything. The only way around was to create an empty multi site in Local, and then manually importing the database with Sequel Pro.

Having a look at the logs shows that MySQL fails with a large database dump. Maybe running out of RAM internally in the docker container.

The large site export however is working fine in Local.

Local by Flywheel 2.1.2
Mac OS X 10.11.6

Now upgraded Local to 2.2.2. But did not have the “chance” to test that.

Hi Clay thanks for the reply, I thought it would be easier if I just record a screen of what’s happening. Here you go

Thanks a lot Maria-Ines

Hi Maria,

Thanks for the screencast!

Unfortunately, it looks like WP All in One Migration uses a custom compression algorithm that Local does not support at this time.

Your best bet is to use a tool like the following to manually extract the .wpress file:

Once you do that, you can re-compress it as a zip and import it into Local as long as it contains at least one .sql file and the wp-content folder.

If you don’t want to go that route, it looks like the other alternative is to purchase a Pro license of All in One Migrator.

Hi Maria,

In the All-in-one plugin edit the file called constants.php in that file find " max file size " and put a zero at the end of the numbers there this will make the upload size to 5GB

I have done this and it works fine.

hope this helps

Im having an issue mirating my local site to another host. I keep getting the "Unable to open file for writing. File: /app/public/wp-content/plugins/all-in-one-wp-migration/storage/ " Im so new to this, so clarity is extremely needed. Thx

I got the same problem today for one of my client website. Then I installed an older version 6.64 of the plugin from another website of mine []( and it works fine.

It’s simple… download the Basic version of the All-in-One WP Migration Import plugin and install,
It increases your upload limit to about 512TB.

Where do I put the 0

define( ‘AI1WM_MAX_FILE_SIZE’, 536870912 );
