After upgrading the Manager to 7.0.2, you must then upgrade all Agents.
An inplace upgrade of BESR Manager to 7.0.2 does NOT upgrade the EasyInstaller packages to the 7.0.2 Agent versions. You must do one of two things:
1. Uninstall BESRM and install fresh (two reboots required)
2. Delete existing EasyInstaller Packages and create new BESR and Management Control EasyInstaller Packages using BESR 7.0.2 Prod CD.
A BESR 7.0.2 Patch Only is available

Please read all documentation provided and link to the above Patch Only document.
