system release notes before

It moves the data of the current system to the new system

You call that from the old system the resource of the data and the program etc is moved in the new system “movement”

When collating ends, it directs to production release finally and enters into preparation.It will keep seeing the point of caution before the release.

In case of system reconstruction, from the old system the software resource of the data and the program etc, the hardware resource of the personal computer and the LAN circuit etc must be moved in the new system.This is called “movement”.Especially being difficult with data movement, there is no old system and begins and when it systematizes even, data movement occurs.

From the database of the old system, the data is moved to the database of the new system generally.It is it could move simply, but first there is no that kind of case.When order of data elements is substitutes, it is simple, but when new data elements it increased because it does not exist in the old system, there is no other choice but to input with power skill.

For example, the “claim file” and the “payment end file” is an old system, when each one business processing is done independently, there is no key item which ties the file.if you change the specification in the pre-payment reconcile the claim file in the new system, not simply to transfer the data of the old system will not go. the old system2one file1visual check of each, data must be migrated to the new system while scrubbing deposit the claim file by sheer force of numbers.

difficult to validate the legitimacy of that migration has been completed properly

if you have migrated in the human wave tactics and brute force, check the integrity of the data over the effort has not occurred or miss

the validity of that the migration went well from the old system to the new system, be difficult to guarantee if the problem. will develop a program for migration, if lurking is a bug in the program, to be discovered after the production. if migration is not forced to rely on human wave tactics and brute force, about the integrity of the data so you still misses, you will need to check over the considerable effort.

in the tokyo stock exchange2005years11system failure occurs in may. unusual situation that the complete suspension of trading in the morning. cause an error in the migration program from a test to a production environment, mistakes become apparent migration was in the month-end processing. if this is the annual processing1mistake will become apparent in years ahead.

migration is also the case for the first time to systematize. ledger master of the new system from suppliers and customers ledger (ledger) you must create a database that will be the. if the current paper-based, data must be migrated by sheer force of numbers this also.

M&Awhen integrated companies such as, system integration will occur. some of the company if you want to integrate into any system, to build a new system, you may want to migrate from the system each of the two companies. i see in complexity it is often the system, borrowed time and effort it also complicates the migration. migration did not work, be later than originally scheduled production release is not an unusual story.

there is a migration of running in parallel with the old system all at once migration and

old and in the field is to be run concurrently, labor has occurred twice to enter the new system, more work

how do timing at which the transition is important. if you can cover by manpower when there was something small systems, or, to migrate to the new system from the old system all at once at some point.

you may of course you have trouble. in ana2007years5server system you are using to connect to host in may3units2has been updated over the week. however27day (sunday) reservation and ticketing system problem occurs with the. processing capacity of the terminal significantly decreased, reservation and ticketing procedures began to hitch. server3recovery was let back into the pre-migration server and software units, 130flights canceled, 306flight1out a delay of hours or more, about7ten thousand9300had an impact on human.

usually will stop the old system from the new system until the problem is solved by moving in parallel to the old system and new system. since the run concurrently, operating costs will increase. old in the field, more work effort occurs twice to enter the new system. as well as forms2one received, you must check whether the new system up and running well in the forms of the old system.

and program development for data checking between the old and new systems, it takes effort, such as developing a program for the bridge for use with the old system and the customer table of the new system. even in the event of trouble if you put in the new system up and running in parallel, you can leave insured so quickly revert to the old system.

for systems such as banks, you may be migrated to the branch unit. bank of tokyo-mitsubishi, ltd. andUFJthe merger of bank of tokyo-mitsubishiUFJthe bank has become, unit was held at the branch office system migration. this is because when you migrate all at once got into trouble, in order to localize the impact but will affect all branches. because it takes time but, migration costs will increase.

here is a step back to the old system of production and withdrawal criteria

if it be to verify the degree of production is completed it is determined that the unreasonable delay the production back to the old system

sun-production (cutover) although the new system to verify the completeness of the final for the, if you leave it to this production that are deemed unreasonable delays the production back to the old system. even if it is determined that the process is performed in a production environment inconsistent migration fails.

about the migration progresses, time consuming work of restoration work to the old system becomes more complex. check provided several points during the migration process, you have made or discontinued when the criteria has been in production readiness state at the time of check points what. you have also made these steps to return to the old system at the time of checkpoint.

many companies do not have a clear withdrawal criteria this. is the extent to communicate with suppliers to production delays related to small business if, sun or production has been reported in the magazine industry, such as the system becomes slightly larger. psychology and bad information, such as the scene works so do not want to increase leads to resignation of the director in charge delay in production, production remains low and will mature. this helps to minimize these problems publicly once you have a clear set of standards and abort the reporting system.

first national industrial, fuji, of nippon kogyo3bank restructuring is, mizuho bank is2002years4month1it was opened on the day, remains low because it is running a matureATMfailure is. confusion1continued more than a month, business improvement order is issued from the financial services agency, damage due to system failure18climbed to about one hundred million yen.

place to build a support system

reward someone for his services to launch attracted members to the production time is calm

put an end to the migration work, commissioned the development and production finally is time to greet theITremaining members of the vendor is not the most, we are developing a different system in another project.

when trouble has occurred in production, since humans were the most detailed programs and the detailed designITyou get a support system teamed to ask the vendor. is a contact network and mobile phone number i wrote a nutshell. i have to worry about the trouble after the production date and production side also made, on the other hand if nothing you have done well. was safely reached the production. thank you is pleased to send a message and.

if you determine that a high degree of completion, there are a small number of companies invited to perform the ceremony all members to the sun-production. since the problem occurs with less than production in most cases greater than, thank someone for his trouble that has been done well to launch attracted members by the time production is calm.
