SAP R/3 –> ECC EHP5 Upgrade
SAP R/3 –> ECC EHP5 Upgrade
The upgrade program upgrades an ABAP system using a system cloning and switch procedure.
This procedure installs a copy of the system, the shadow system, in parallel with the original system.
The shadow system is used to update the affected software components and to install the additional components, while the original system is still in production operation.Operating two instances in parallel places increased demands on free space in the file system, in the database, and on the system resources. No precise guidelines can be given for the duration of an upgrade
The duration of the system cloning depends to a great extent on the amount of data, the database system, and the hardware and can take several hours.
Although the system can still be used in production operation, you have to take into account a possible performance decrease during this cloning process.
If necessary, some parameters in the production system might need to be adjusted to enable you to operate the production and the shadow systems in parallel.
