Subject Re: Utilizing a slice for online migration
Date Sat, 31 May 2014 07:17:03 GMT
Yes, you are on the right track.
I have considered that Slice can be used for data migration. Read data from
one Slice and if the data is touched, write it to another. 

Nowadays, I do not spend enough time on OpenJPA to help with you some real
code/prototype. But with little digging (especially where Slice writes the
same record to multiple databases for @Replicated types) -- you can use it
for online migration.
