Clean up /data01/avamar/src/

Hello,

I have a lot of old source in /data01/avamar/src on my Avamar node like :

avaim_FULL_7.3.1-125_1
avaim_FULL_7.5.0-183_1

avaim_FULL_19.1.0-38_1.tgz
AvamarBundle_SLES11_64-7.1.0-370.zip
Avamar_Client_Installers-19.1.100-38.avp
UpgradeClientDownloads-19.1.0-38.avp
RPS_TLA_Avamar_Updates_19.4.0-124_Rev1.tgz
clients_7.1.100.370

They are all related to old Avamar versions.
As we're running a later version, can these files be safely deleted?!
Thank you.
Regards.
