Was not able to find answers to what I wanted to know, and also wanted to see what their system was like to used, so I paid for a years use, and if it works out, will use that account as a temporary store for sites, and then take out a 4 year contract to replace the IONOS account.
I have tried their free WP migrating service, but it seems slow.
However, I have copied several sites across, and it is fast.
Actual access to the sites is much faster than IONOS.
The last one I have just done took 7 minutes, to backup the site from IONOS to google, to create a new subdomain on Hostinger, to install WP on that subdomain, then to install the backup software, then restore from google drive.
Never had it so easy or so quick, and their control panel is a pleasure to use.
And SSL is free
