How should the big Notes database be divided?

The number of documents have become large after using a Database over 2 years. Then, the size of the database became big, too.

I want to divide the database into 2 databases on the basis of a category.

Which should I use the replica or the copy of database ?

But,

the former has a risk of the unexpected deletion of a document during replication after the document is deleted from a database of two replica,

while

The latter has the problem of the disappearance from the links.

What should I do?

DB size is too big to reach 500 MB, the limit defined in my company. I must divide the database accroding to my company rule.

I want an document like a guidline to perform the division.
