I am trying to update my Magento 2.3 instance to 2.3.1.

So I'm trying to finish the update and upgrade checklist,

but when I get to the step:

Set a value for DATA_CONVERTER_BATCH_SIZE, I copied the command on the page export DATA_CONVERTER_BATCH_SIZE 100000

And I get the error

bash: export: '100000': not a valid identifier

What should I do to fix this so I can update my installation?

To set the variable on Ubuntu, enter the following command as the Magento file system owner in a bash shell prompt:


output: No output will be seen on screen, to see exported variable use below command.

  • Can you explain why this works? Thanks! I'll do this before I try to update again Apr 25, 2019 at 14:02
