This question has arisen at Redcar & Cleveland and, no doubt, other authorities. It has been suggested (not just here) that ISA databases can be built up from one or more databases already maintained by local authorities. My own view is that any data sharing must be on an individual basis with justification based on one or more of the Schedule 2/Schedule 3 conditions. However, colleagues have suggested that Section 12 of the Children Act 2004 might allow mass migration (though I'm unaware of any regulations made as yet). If regulations are made under S12 I suspect that challenges from parents might follow.
