Migration Issues - out of memory Errors

I keep getting the below error while trying to run the Migration tool: 

 

./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)

I have found numerous posts online saying to set memory_limit to 2048MB and it is . 

I have 0 swap file and Aspiration Hosting is no help with this issue. They said I need to manually migrate the data over - I haven't even found any information on doing that. 

 

Any information would be great?

Hello @rick_wade ,

 

 

Possible solutions could be

  • to set PHP > memory_limit = -1
  • In data migration tool > config.xml <bulk_size> = 1000 or 500

 

Increasing the server's memory from 4GB to 8GB, then assigning 7GB for PHP fixed the issue.
