Hello. Thank you for contacting the Toolset support.
Toolset Types plugin version (2.2.9 from the year 2017) is really old version and outdated one as after that we release number of major release and added number of new features.
Before you update the Toolset plugins to latest official release version:
*** Please make a FULL BACKUP of your database and website.***
But before you update any plugin I recommend you to take full backup of your site so in any worst situation you can restore it.
However - I suggest you should create a staging site first and on staging site you should run update first and once you see everything is ok and working on the staging site then you should go ahead and update it on your production site.
We publish the Types 3.X.X with the new many to many relationships and we have added the number of new features to this major release almost nine years ago in 2018.
