TRS22 will install as a separate install and will not affect any other installed versions. When you install 22 it will put the data folder in the C drive as the default location like all the other versions. If you want to use your old TRS19 data make a copy of the build folder located in your TRS19 settings/install window. Paste it in your second drive and re-name it or make it easy to see it is TRS22. Open TRS22 settings/install and change the path to the new build folder and do a DBR. You may need to download some content from the content store like additional Tane assets. The TRS22 build folder that was installed on the C drive can be deleted.
