Sysdump and unmirroring

I'm researching on how to unmirror a set of mirrored drives as this should enable me to do a failsafe patch install. My current install has 2 disk with all LVs mirrored except the sysdump LV.

This is the bit that confuses me as some seem to advise removing the sysdump from both drives (Patch management in AIX - IT Community) whilst others advise migrating the sysdump LV to the other disk before splitting the mirror.

Is there any reason to choose one option over the other?

NAME
SVK::Path - SVK path class SYNOPSIS
See below DESCRIPTION
The class represents a node in svk depot. root Returns the root representing the file system of the revision at the anchor. Give optional pool (null to use default), otherwise use the internal root of the path object. Be careful if you are using the root object but not keeping the path object. same_repos Returns true if all @other targets are from the same repository as this one. same_source Returns true if all @other targets are mirrored from the same source is_mirrored Returns the mirror object if the path is mirrored. Returns additional path component if used in array context. normalize Normalize the revision to the last changed one. as_depotpath Makes target depotpath. Takes $revision number optionally. path Returns the full path of the target even if anchorified. descend Makes target descend into $entry universal Returns corresponding SVK::Target::Universal object. depotpath Returns depotpath of the target copy_ancestors Returns a list of "(path, rev)" pairs, which are ancestors of the current node. nearest_copy(root, path, [pool]) given a root object (or a target) and a path, returns the revision root where it's ancestor is from another path, and ancestor's root and path. related_to Check if $self is related to another target. copied_from ($want_mirror) Return the nearest copy target that still exists. If $want_mirror is true, only return one that was mirrored from somewhere. $self->seek_to($revision) Return the "SVK::Path" object that $self is at $revision. Note that we don't have forward tracing, so if <$revision is greater than "$self-"revision>, a "SVK::Path" at <$revision> will be returned. In other words, assuming "foo@N" for "-r N foo@M" when N > M. as_url($local_only, [ $path, $rev ]) Returns (url, revision) pair. node_id () Returns the node id of this path object. SEE ALSO
