BSP and U-boot Upgrade with Quartus Version Upgrading

Dears,

My customer is using Quartus 18.1 Pro with 1SX110. Currently, their application software is running well.
Now, they need to upgrade the Quartus to 19.2. Whether they must upgrade the socfpga.qsys, bsp and u-boot? If not must, what’s the potential risk?

Thanks a lot.
