Migrating a better performing domain to a less well performing domain

[ChristiMc]

I have a customer who has many domain names and assets but she's wanting to consolidate some of them to help her simplify things for her customers but mostly she wants to build up her website through which she sells products.

Grief Reflection - www.griefreflection.com is a personal journal that she's keeping to process the impending death of her husband and it's also linked to her business website which sells healing from grief types of products.

Storybooks for Healing - www.storybooksforhealing.com is the website through which she sells workbooks and memory books for people who want to keep the memory of their loved one alive after they've gone.

I've setup both of these domains as campaigns and have been looking at the metrics for both.  The grief reflection blog out performs the storybooks for healing website.

If we merge the two then the Grief Reflection blog would likely become a subdirectory under www.storybooksforhealing.com and be more fully integrated which she thinks will help her visitors not get confused while navigating her website.

www.griefreflection.com has 12,637 links while www.storybooksforhealing.com has 1,462.  Also, Google has indexed 380 pages of Grief Reflection and only 100 pages for Storybooks for Healing, though that may be because there are fewer pages to index. Grief reflection also has a 4.36 mozRank and 5.30 mozTrust, where Storybooks has 4.13 mozRank and 5.15 mozTrust.

Should I counsel her to keep these domains separate?  If not, would simply setting up 301 redirects from the www.griefreflection.com domain name to the new subdirectory under www.storybooksforhealing.com be the way to go?

Thank you ever so much for any wisdom anyone can provide.

If I owned these two sites and my goal was to strengthen the storybooks site then I would 301 redirect griefreflection page-by-page into a folder of storybooks.

I believe that the rankings of the storybooks site would benefit.

Hello and thank you for your quick response!  She'll be happy to hear it and I'll be sure to 301 each page from the migrated site to the new one.

I appreciate your help!
