Actually, it is probably better to make a new swap LV, activate it, and
then deactivate the old one (assuming you have enough disk space to do
so).  Otherwise, you may run out of memory if you don't have a swap

The other alternative is to simply have 2 or more swap partitions.  If
they are created with equal priority, then they will both be used.  There
is no problem with having multiple swap partitions.
