Tortoise SVN merge of 2 repositories

Question

I have 2 repositories that I would like to merge. I would like to take the 1st repo [PRIMARY] and pull in all the content from the 2nd repo [SECONDARY]. They don't share content so I don't need merge different versions of the same file. I would like to retain file history of the elements in SECONDARY when they are pulled into PRIMARY.

How would I go about this using TortoiseSVN 1.5.2?

Answer 1

In short: You can't (at least with Tortoise).

But the Subversion FAQ describes a way (Using svn dump and svn load).

Answer 2

I don't know that you can merge the histories (PRIMARY will have r123 and SECONDARY will have its own r123) but you could setup an external.
