Synch Imported Elements from DB Schema

[pittagentskip007]

Hi all,

So I'm new to EA and have imported tables/procedures/etc from my software's Oracle DB into EA a month ago. Since then, I've done some work linking tables to requirements and other such things. Now I want to refresh my previous DB import but am unsure how to do so WITHOUT losing all the notes/links I've attached so far. I'd just try this but am too afraid to do so  without some insight from someone who knows better? :-/

Also, what happens if I import the same schema from a different physical DB instance? For example, my schema name is Foo and there are three copies of it: one for TEST on TEST.WORLD, QA.WORLD, and PROD.WORLD.

If I imported first from Foo @ PROD.WORLD but wanted to refresh EA from Foo @ TEST.WORLD would it recognize the tables etc as being the same and synch or would it create new?

Thanks!
