reset - masterkey

i want to do a platform migrate - but the UCS file has encrypted passwords - and i dont know the source BIG-IP system master key password or passphrase -- so the option is - to reset it on the source and re- generate the UCS - reset the passphrase on the new platform to match the source and import the UCS

 

QUESTION -- does resetting the Master Key have any impact on any other config -- my concern is for the Source system - if i reset - is there a potential of any issue Thank s
