Phase 3: IMPAX 6.5.3 and WEB1000 coexistence
(Topic number: 6642)
IMPAX 6.5.3 and WEB1000 run as separate systems, but with image routing based on IMPAX routing
rules. However, data currency does not exist, so data does not remain synchronized between
IMPAX 6.5.3 and WEB1000.
WEB1000 users start to be trained on the IMPAX 6.5.3 system.
Phase 4: Initial set of WEB1000 users switch to IMPAX 6.5.3
(Topic number: 6641)
After two months of operation (for example), two months’ worth of new studies have been sent to
IMPAX 6.5.3 and curated to the IMPAX 6.5.3 web cache. The relevant priors for the new studies
have been retrieved from archive and curated to the IMPAX 6.5.3 web cache.
At this point, some WEB1000 users can begin to use IMPAX 6.5.3 instead. Unavailable studies have
to be retrieved from archive and be curated, which causes a delay.
Phase 5: More WEB1000 users switch to IMPAX 6.5.3
(Topic number: 6640)
The situation is the same as detailed previously, except that fewer studies should be unavailable to
the IMPAX 6.5.3 system. More WEB1000 users start using IMPAX 6.5.3.
Phase 6: Transition complete
(Topic number: 6639)
All WEB1000 users switch to the IMPAX 6.5.3 system—ideally when all data in the WEB1000 web
cache is also in the IMPAX 6.5.3 web cache.At this point, the site can stop routing studies to WEB1000
and WEB1000 can be decommissioned.
Developing a core server plan
(Topic number: 6708)
We recommend specific hardware and software for the various IMPAX 6.5.3 cluster components.
Use these requirements to assess which existing servers to keep and upgrade, and which to replace
with new servers. Based on the requirements in IMPAX hardware and software requirements (refer
to page 32) assess your current IMPAX server stations. List which hardware and software components
on these stations must be upgraded to make the station function with the IMPAX 6.5.3 software.
Compare the time and costs of these upgrades against the time and cost involved in purchasing new
hardware and installing the appropriate software on it. Use this to determine which stations you will
reuse and which will be replaced.
