We have a scenario, where in one of the drive is spanned across 2 arrays , its not a database server its a stnadalone SAS server. But one of the array is getting decomissioned and devices are part of spanned drive. how am i suppose to proceed with mig

There are 2 arrays "A" and "B" both are vmax arrays, server in question has luns both from array A &B. A is getting Decomissioned and B is my target array for migration. How am i suppose to procedd with migration. There are chances of data curruption, if devices are from 2 different array.
