The message "enabling bpe feature on target instance" points out to the issue already: Business Process Engine (BPE) was not enabled in Target Instance. 


As part of IRT prerequisites, BPE should be enabled in both Source & Target as per KBA 2791468. Enable the BPE from the Target Provisioning under Company Settings > Enable Business Process Engine

Under TLS-26589 our ENG team is working on an improvement to the IRT tool to ensure that this get automatically fixed.
