how can I run a set of changeSet in transaction

Hi

I need to run a set of changeSet in transaction, how can I do it ?

Or maybe a way to “–changeLogFile update” in transaction.

I know that each changeSet has a transaction, but I need only one transaction for all.

Thanks

I was thinking in use the updateSQL to an output file, take this file and put it all in one single changeSet as sql.

But if i di’t it, I’ll lose all my preCondition.
