We are in process of creating a different Language Versions of a Website and trying to figure out the best/recommended approach.
what are the major differences b/w live copy blueprint and Language copy of CQ ? which one is recommended in which ? any pointers on this would be appreciated.
The language copy tool is a one-shot tool to create pages under a certain structure. It has a nice UI for it. But that's it.
The MSM blueprint/livecopy concept is much more powerfull, because it has live connections between the blueprint and the livecopy. It does not only allow you to easily create livecopies, but supports you also in maintaining the relationshop between these. So you can easily detect, that the blueprint page has been updated and needs to be rolled out again. Or that there are conflicts, because both blueprint and livecopy have been updated independently. And so on.
From my perspective the language copy tool should not be used, because with creation of language pages the "fun" has just started and the real work is just ahead.
