https://knowledge.broadcom.com/external/article/136964/dxca-spectrum-upgrade-path.html
After transferring all files to the new server and loading Spectrum install over it, the installation failed:
Gives error saying our version 10.2.3 is NOT supported for 20.2.7 (10.4.3.0).
Even though the KB article say’s its clearly supported for 20.2.7 (10.4.3.0).
Release : 20.2.x
ssdb was un compressed. After compressing ssdb file, the install completed successfully.
