Is there any way to upgrade the SEP client to the new version without uninstalling the old one?

What  version you are on?

if its supported then you wil upgarde the SEPM first, buy running the new install on top of the existing one and then use the auto upgrade features. You dont need to do a complete uninstall /reinstall

Simply running the new version installation on the old client will start the upgrade process - removal of the old version is not necessary.

Hi,

You can simply install the new version on top of existing version it will upgrade to the new version.

Hi,

SEP 12.1 employs a side-by-side, replace on reboot installation strategy. Side-by-side means that new files are written to a new folder, referred to as a silo, isolated from the existing operational folder. Because the two versions are separated from each other, during a migration the older software is left running unchanged until the next reboot.

The primary benefit of side-by-side installation and replace on reboot is that the system continues to be protected by the existing software until the new version is in operation after the reboot.

This technique enables you to change the normal portion of the installation path during a migration, when applicable.
