Some members of the legacy iOS community (r/LegacyJailbreak) have attempted to resurrect WhatsApp on iOS 6 via:
Users attempting to install an old WhatsApp IPA file (extracted from an old iTunes backup or an IPA repository) will face two immediate barriers:
The WhatsApp IPA for iOS 6 is an artifact of mobile computing history. Its architecture—reliant on 32-bit ARMv7 instructions, heavily textured UI assets, and deprecated cryptographic standards—illustrates the rapid pace of mobile OS evolution. While the binary can be preserved for archival purposes, its functional utility has been severed by server-side protocol updates and TLS deprecation. It remains a valuable case study for digital archivists and software engineers studying the evolution of mobile app architecture. whatsapp ipa ios 6

I understand you're looking for information about running WhatsApp on an older device (iOS 6) using an IPA file. However, I need to provide some important context first. Some members of the legacy iOS community (r/LegacyJailbreak)
WhatsApp for iOS 6 was compiled as a 32-bit binary. An analysis of the Mach-O header would typically reveal support for:
Note: Modern iOS devices (iOS 11+) have dropped 32-bit library support, rendering this binary unlaunchable on current hardware without emulation. References:
The SC_Info directory inside the bundle contains the Manifest.plist and signature files. When a user downloads the IPA, Apple encrypts the executable section of the binary using the user's specific Apple ID.
The iOS 6 operating system supports TLS 1.0 and early TLS 1.1. Modern WhatsApp servers mandate TLS 1.2 or TLS 1.3 for secure connections. Due to compliance requirements (PCI-DSS, GDPR, etc.), older SSL/TLS ciphers have been deprecated. Consequently, the iOS 6 client cannot perform the initial TLS handshake with the WhatsApp registration server, resulting in a connection failure.
WhatsApp no longer supports iOS 6 — the last compatible version was WhatsApp 2.12.7 (around 2015–2016). Even if you install that old IPA, WhatsApp’s servers will likely reject connections because:
