Assuming you can map all historic data from the old system to activiti, I don´t think stuffing act_hi_* tables with all that data is too bad, since it´s a one-time task after all.

One thing that you can do in order to easily find old instances is to use a different process version for them. Just deploy your new process twice, and use the first process id that you can use as a basis to populate historic tables.

Hi,

In case when it is not possible to map legacy data to the ACT_HI_* tables you can:
1. Keep data in legacy system and get history from the legacy system before it is archived.
2. Extend act tables to support your needs.
