all migrators work around same principle but spupgrade did a very neat job of migrating over joomla/k2/vm around 600 products without any hitch except for the vm images which i would do one by one. no prob. but you see spupgrade did a fantastic job regarding content, layout etc. so neat and perfect . the support guy Panayiotis - wow - never gave up- paid around $50 singapore dollars for the extension - worth every cent.
