Moving VIOS, LPAR's, HMC to different subnet

Hi,
Just joined to new company with one Power 720 Express (8202-E4C) server and have no much experience with IBM systems.
I am trying to move everything I mentioned to different subnet as required by customer contract (currently sitting on same subnet as company lan). Access to this subnet will be controlled by firewall (dedicated physical port).
My idea was first to move HMC than VIOS and LPAR's at the end. Through HMC I could use console access to VIOS and LPAR's so I can control IP settings not worrying losing connectivity to them.
First I moved HMC (management) port and it works as expected (I can access it from old subnet).
Problem is that HMC now can not connect with console to VIOS and LPAR's any more. (Internal error, unable to send command to the managed system)
So my question is how HMC communicates with VIOS and LPAR's?
How can I ensure not to lose console access capability?
Do I just need to configure VIOS and LPAR's with IP's from new subnet and hope that they would be accessible again via console access?
For HMC move I changed IP address and default route on interface. On firewall side for the transition period both subnets can talk to each other - no restriction/blocking).
Thanks.
