Hi,

Our system is currently working under 1.2.13 and we would like to upgrade to 1.4.9. I notice that there variables and functions that are deprecated, will they still work as is on 1.4.9? Thanks.

Hi You need to get the upgrade notes and o through your dialplan and remove any that are in there and replace them with the new version.

Main ones to go are astdb control and timeouts.
