a customer of us have a clearsea server 4.0.7 and a lot of 220 express system registered to them.
is it safe to upgrade to 5.0.13
do I need to make changes in the 220 systems?
It depends on how they are registered.
If in Independent Mode (H323/SIP/LDAP), then you will lose the LDAP Server in ClearSea, so I recommend you move them to Integrated Mode before upgrading to CSS 5.0
If already in Integrated mode, make sure your 220s are on 5.0.x before you upgrade the CSS.
