A high temporal resolution magneto-optical system is employed to observe the time evolution of the vortex structure in a Bi2Sr2CaCu2O8 crystal after a sudden application of a magnetic field H3 in the range around the vortex solid-solid transition field. For low applied fields, initially Bean-type profiles are observed, rapidly relaxing into the equilibrium state of the quasi-ordered phase. For high fields, a boundary between two distinct vortex solid phases coexisting in the sample is clearly observed.
