How can I correctly use initial temperature conditions from an existing s-s study for a transient study?

When creating a new transient thermal study, I am attempting to use initial temperature conditions from an existing study but I am running into issues when I try to run the new transient study. The error code that I am getting reads, "incompatible initial conditions". What does this suggest is wrong?

I can post up my files if anyone is willing to look at them.

Thanks!
