moving ESXi host into cluster

Hello all.

I have ESXi host that is currently not in any cluster. It has some Datastores attached.

I need to move that host into a cluster that has diff. datastores and i just need for the new ESXi host to inherit cluster datastores.

Do i need to unmount datastores before moving the host or if i just move the host it will inherit cluster datastores automatically and current ESXi datastores will be removed.

Thanks in advance
