Hi ,
1 )
content stored database is moved from 8.2 to 8.4 , My package is published only at 8.2 , when i opened 8.2 reports in 8.4 where will package pointed to ? it is 8.2 content store or 8.4 content store ? to point it out 8.4 i do ineed to publish the package in 8.4 ? .
2) In framework manager "Allow enhanced model portability at run time" .What it does ? will it affect in migration ?
When you install 8.4 and you point it to your 8.2 content store, it will upgrade your content store to 8.4. No package needs to be republished.
i don't know for #2 but it should not be a problem
