Our budget has finally allowed me a new "all singing, all dancing" server and it has physically arrived. Two questions if I may -- and if I'm off topic, plz say so: 1) The system (Ubuntu 11.04) is being installed on a SSD (solid state drive) which recommends keeping "writes" to a minimum for longevity. This obviously includes logs, etc, but not necessarily the sql database. A quick "find / -iname" on the sandbox (Koha 3.02.05.000) for '*koha*' is enormous. Does anyone have to hand a list of "system" versus "run-time" directories and files? I'm particularly curious about Zebra (which I do not fully understand) as it appears to be proliferous and ubiquitous. 2) I have stabilized a partially customized Koha 3.2.5 which is close to meeting our needs. Koha 3.4 would be my choice on the new server (and I'm not worried about cosmetics -- CSS, etc) but how bullet-proof is the data conversion (as of now about 80,000 records)? I truly want Koha to be our long term data solution for our holdings, but am still wet behind the ears with Koha, so all help would be appreciated. Many thanks in advance for all suggestions.
