5 attempts, can't get the migrator to complete

Hi guys,
I’ve tried 5 times to get the migrator tool to work for one specific site. I’ve used your migrator for other sites and it’s amazing, but this particular one is just a small nightmare and I need help.
It appears to time out, and start generating errors after a certain number of attempts. The first attempt was the best – managing to get the database, themes, and ‘others’ over, but no plugins and no image files. I manually re-installed the theme and plugins; the image “names” came but not the actual image files. I can’t seem to replace those and need to try this process again.

The site we are migrating from is : https://freespirit.administration-network.com/
To: https://freespirityoga.043cb22.netsolhost.com/

I’m debating whether or not the best course of action is to manually just relink all the images, but that will take me hours and hours and would far prefer to just have a fast restore take place. Ideas?

Thanks again,

Jen
