Hi @Ayeli Zauda
You can use Test Plan, one for each version. You may also clone the Test Plans if they are similar and only change the versions associated with the Test Plans.
Would you please check our documentation on the Test Plan: https://docs.getxray.app/display/XRAY/Test+Plan
Please get in touch with Xray Support (http://Xraysupport.getXray.app) if you need further help.
