Hi SDNites,

I am working on few scenarios where TLS 1.2 is mandatorily required. Can you please let me know,

1. Which SAP PI scenario works on TLS and which one works on SSH. As per my understanding SFTP works on SSH only while all HTTP / HTTPS sceanrios works on SSL / TLS. Please confirm.

2. If we upgrade to TLS 1.2, do we need to test all other servers connectivity if they support TLS1.2 or if it is backward compatible that means if some server still supports TLS 1.0 then the outbound handshake connection from PI will automatically be on TLS1.0. Please let me know your comments.

Regards,

Abhi

Only for SFTP the SSH is used, but when coming to SSL some of the adapters are SOAP/REST/HTTP/AS2/OFTP/FTPS/SFDC/SFSF etc..

2. If we upgrade to TLS 1.2, do we need to test all other servers connectivity if they support TLS1.2 or if it is backward compatible that means if some server still supports TLS 1.0 then the outbound handshake connection from PI will automatically be on TLS1.0. Please let me know your comments.

Yes testing for existing connections is recomended some legacy system may still be supporting TLS 1.0 /TLS 1.1.

But there is a option that PI can support TLS 1.0 /TLS 1.1 and TLS 1.2. Check this
