Not able to use backups of RTC 3.0 into RTC 3.0.1

Hello experts,

One of my company's client is using RTC 3.0.1. Previously they were using RTC 3.0 and after that they did,t upgrade it. Presently they are having fresh installed RTC 3.0.1 and I want to use the RTC 3.0's backup in RTC 3.0.1.

Can you please tell me how to use wrokitems of previous version in Latest version of RTC without using any up-gradation strategy??


Thanks
