First off, i suggest updating the OS to 5.3 if possible anyhow. 5.2 is not only outdated and no longer supported, it is also a nightmare of bugs and most of them are corrected in 5.3.

Regarding your question: you will need downtime for this: change the VGs to "enhanced concurrent", then varyoff them on their original system and do a "learning import" on the other system. (Corollary: do yourself a favour and make sure you have the same major number for the VGs across all your systems. This makes administration easier.)

Define your new resource groups based on these VGs then and do a "extended verification and synchronisation" via C-SPOC.

I hope this helps.

hb_takeover

HB_TAKEOVER(1)							 General commands						    HB_TAKEOVER(1)

NAME

       hb_takeover - issues a failover request to the cluster manager

SYNOPSIS

       hb_takeover [all|foreign|local|failback]

DESCRIPTION

	   Warning
	   This command is deprecated. It is only suitable for legacy Heartbeat clusters without Pacemaker enabled. In Pacemaker-enabled clusters,
	   the crm(8) shell supports switching individual nodes into standby mode, and replaces hb_takeover.

       /usr/share/heartbeat/hb_takeover issues a request to the cluster to move resources to the node where it is invoked, from the other node.
       Issuing hb_takeover on the current node is equivalent to performing hb_standby on the other node.

CAVEATS

       hb_takeover is only usable in R1-style configurations (i.e., those configured using the haresources file).

SEE ALSO

       hb_standby(1), heartbeat(8), cl_status(1)
