Please notice that when you want to run HANA 2.0 SPS07, you need defined OS levels. As you can see RHEL7 and SLES12 are not certified for SPS07. The SPS07 release of HANA is the basis for the S/4HANA release 2023 which is my recommended go-to release for the next years. Keep in mind that you have to go to SPS07 when you are running currently SPS06, because it already run out of maintenance in end of 2023.
SLES12 SP5 for SAP will run out of maintenance at the end of October 2024. To be supported you have to pay for LTSS because it is the final SP of SLES12 there is no ESPOS - no overlap support for this one.
Please plan your updates if you are still on SLES15 SP2 due to end of maintenance by end of this year.
Attention: There is currently an ongoing issue with SLES15 SP06 and ADS (Adobe Document Service) for onprem usage. Please check note 3522913 - ADS on SLES 15 SP6: Texts are not displayed in PDF after upgrade.
