Can I use different versions of 'Processor Manager' and 'Processor Nodes' in Paramics?

Product Feature: Processor node
 
No, It is recommend that 'Processor Manager' and 'Processor Nodes' used together should of same version. Although different version of  'Processor Manager' and 'Processor Nodes' used together will not throw any error or warning message, but the results may be affected.
