Hi Experts
We are planning to upgrade our system from ECC6.0 -EHP4 to EHP6.
Source - ECC6.0-EHP4
Target - ECC6.0-EHP6(Enhancement pack6)
Current ECC version -
SAP_BASIS 701 0014 SAPKB70114 SAP Basis Component
SAP_APPL 604 0013 SAPKH60413 Logistics and Accounting
We would like to know during the project if we can do a transport
between upgraded development ECC6.0 -EHP6 to non upgrade production ECC6.0-EHP4.
We have data from note 1090842 and 1273566.
But last 10 lines of note 1090842 are contradictory wherein on one side it says you can do transports between Releases 7.0*, 7.3* and 7.4* and
on other it says it can be problem if support pack levels are different on same release.(if problem can happen on same release with different pack
level then there are greater chances of issues between different releases).Note 1273566 is clear and suggest no issues exist yet for
technical and logical transports between suggested version 700/701 to >=702
Also below is the extract from SUM guide - (SUM-1.0-SP07)
RECOMMENDATION
We strongly recommend that you perform transports only between systems of the same release or enhancement package level, and where the same business functions are activated. If you do not follow this recommendation, you do so at your own risk regarding potential problems.
Please suggest if we need to create Dual maintainance parallel landscape during the tenure of project where two development system co-exist.One
with current and one with upgraded version and changes need to be done on both in parallel.Support fixes and LTO’s go from non upgraded dev to non upgraded prod.
Thanks
