One tenured job to another tenured one?
It is possible.  It is done all the time.  But you should not expect getting any tenured or tenure-track job to be easy.  Advice:  Don't resign your current job until you get the new one.

My experience:
Perhaps the usual would be hiring an associate professor with a one-year probationary period, after which tenure would be determined.  Our university was reluctant to grant tenure immediately, so if we wanted it our chairman would have to make a special plea to the dean or even the provost.  On the other hand, I never saw the tenure denied after the one-year period.
