Yes, it is recommended you move your delegated EGLD from legacy to a Staking Provider due to higher decentralization.
With Staking Phase 4 we aim at continuing the excellent momentum that exists in the staking community at it's the final phase of its decentralization. A strong Proof of Stake economy leads to higher decentralization and increased network security, which in turn attracts more valuable use cases. Staking will get even more decentralized when Legacy nodes will make room for more Staking Provider nodes -> Staking Phase 4.
