Rollover IRA Question (x-post)

[otnemem]

I posted this in BF+I but nobody even responded. I figure more people read OOT, and so I was hoping someone could help me out. THIS IS NOT A GOOGLETARD POST. I've been looking everywhere for this tiny piece of information, and can't find it anywhere...

I just started at a new job, and I can't contribute to my new company's 401k for a year. I'm rolling my previous 401k into a rollover IRA. When I am able to contribute to the 401k, is there any benefit to combining my new rollover IRA with the eventual 401k? Or does it just make sense to leave the money in the rollover IRA and keep two separate accounts (the rollover IRA with money from my old 401k, and then the new 401k through work)?

Thanks.
