PI Connector for Wonderware Historian history recovery

From the  Wonderware historian connector user manual,



Limits in history recovery



The only limitation currently is how far in the past the Connector can recovery. The recovery


points are evaluated at startup for each tag. If a tag recovery time is greater than 4 days in the


past from current time it will be recovery only 4 days of the missing data.


Question is , can we do data backfilling / migration  using PI Connector for Wonderware historian?

Does any one used Wonderware historian connector to migrate data from WWHistorian to PI?

Which one is preferable in data point of view (Not in Asset point) WWHistorian connector or rdbmspi interface ?
