Currently two clusters, one cluster is based on traditional storage, one cluster is vSNA, is there a way to migrate virtual machines in traditional storage to vSAN cluster without shutting down, both clusters are managed by one VC
Yes:
Migration with vMotion in Environments Without Shared Storage
Alternatively temporarily attach the non-vSAN storage to the vSAN nodes (perhaps even just one) or vice-versa e.g. join one of those hosts to the vSAN cluster temporarily.

Just finished a migration like this and it worked without a hitch.
be mindful of different hw architecture can prevent a vmotion.
in our case we had to upgrade to atleast vm hw level 9 to be able to do migration between new intel 61xx series cpu from 26xx v2
