Easy way to find/replace a few pool members

I would probably do this using a script with a loop to run tmsh commands against pools.

something like:

$pools = "pool1 pool2 pool3"

$a = 5.5.5.5:80

$b = 6.6.6.6:80

$x = 1.1.1.1:80

$y = 1.1.1.2:80

for poolname in $pools; do

tmsh modify ltm pool $poolName members add { $x $y};

tmsh modify ltm pool $poolName members delete { $a $b};

done
