Steps
Adopt AdAttributionKit alongside (not instead of) SKAdNetwork, since Apple has not announced a deprecation timeline for SKAN and the frameworks are designed to interoperate.
Implement the re-engagement attribution flow available in AdAttributionKit that SKAdNetwork does not support.
Handle overlapping conversion windows and optional country-code reporting introduced by AdAttributionKit.
Confirm which ad network partners support App AdAttributionKit postbacks versus only legacy SKAdNetwork, since support varies by partner.
Retain your existing SKAN 4.0 postback handling (crowd anonymity tiers, source identifiers, three postback windows), since AdAttributionKit builds on rather than replaces that model.
Known gotchas
AdAttributionKit and SKAdNetwork are interoperable and can coexist - migrating does not mean removing your existing SKAN postback handling.
conversion-value and source-app-id fields are only conditionally included in AdAttributionKit postbacks when specific thresholds are met, similar to SKAN's fine-grained value gating.
Apple has given no deprecation date for SKAdNetwork, so building only for AdAttributionKit risks missing traffic from ad networks or partners that haven't adopted it yet.
