Consolidate 150 domains to 1

[bebetteronline]

Hi!

Just as the questions tell we are looking at a project where we might have to consolidate 150 different domains into 1 (of course with a corresponding page on the new domain). We aim at preserving as much of the linkjuice as possible from each domain.

Any advice on doing this propely? I, of course, see a risk of opening the new domain and just redirecting (301) the old domains to the specific page on the new domain but is there any right or wrong way of doing this?

I might add that each domain has a more or less unique linkprofiles in terms om linking domains, number of linking domains and such.

Our dear friend Cutts has some information on this topic, http://www.youtube.com/watch?v=l7M22teF3Ho but he only talks about 4 domains - which of course seem like a bit more natural occurring phenomenon.  But what about 150 of them?

Anyone got any advice? Is this as much of a no-go that I feel it is?

Thanks!

Edit:

There domains are all owned by the same entitiy, share the same GWT and such.

I would suggest to do exactly as Matt says. Do them slowly and start with your lowest traffic domains/websites. As you see the new site starting to pickup the changes and the affects of the 301 from the old domain and the rankings start to show up, do more...gradually. Rather then all in one day.
