If you continue to use the hiera_hash() function <https://puppet.com/docs/puppet/5.5/function.html#hierahash> then nothing should change for you. It is still documented to honor the :merge_behavior key, and it is also documented to ignore the lookup_options, and to only lookup data from one hierarchy (not three, as Hiera 5 does). If you observe different behavior then you should file a bug report. But that means *not* moving to Hiera 5 API-wise. Moreover, unless you also stick to a single, global hierarchy overall, Hiera 3 style, you will be setting yourself up for problems and confusion. Moving to Hiera 5 means moving to lookup(). If it were me, I'd just bite the bullet and switch over. It may be a bit of a pain to convert hiera(), hiera_hash(), and hiera_array() calls to lookup() calls, but inasmuch as each of these implies a different merge strategy, it should be possible to automate the changes. Moreover, in so doing, you can set up pretty good emulation of the Hiera 3 hash-merge behavior for those lookup() calls that want to participate. In particular, consider doing this at top scope in your site manifest: $hash_merge_behavior = lookup(':merge_behavior', String, 'unique', 'hash') ... and then converting each # original $my_hash = hiera_hash('key', { ... }) to # updated $my_hash = lookup('key', Hash, $::hash_merge_behavior, {...}) . The hiera() and hiera_array() calls can be converted in a similar manner. The one thing to look out for is any three-parameter hiera*() calls, for, to the best of my knowledge, lookup() does not offer any hierarchy-modulation behavior corresponding to what the hiera* functions do with that third parameter.
