BW, PI Upgrades are mandatory when upgrade S4 hana 1610 to S4 hana 2021?

[kimhaniko]

Dear gurus,

I'm planning to upgrade our S4 HANA 1610 system to 2021 next year.

I'm wondering about other sap related systems like BW, PI.

Do I have to upgrade BW and PI also?

We are running S4 HANA 1610, BW(Netweaver 7.5), PI(Netweaver as java 7.5).

Please let me know. Thank you in advance.

I found interoperabilities between SAP systems.
