Objectives ITSM 6 -> 7 Migration Challenges Project Overview Meta-Update: an introduction to an ARS data scripting tool giving ARS developers the power of the API Meta-Update Scripts: ITSM 6 -> 7 Migration Agenda

ITSM 6 to 7 Migrations Completely different and more complex table layout. Many more tables and fields. Much more validation of data fields: Many values acceptable in 6 cannot be used in 7. Documentation sadly lacking. Migration Challenges

ITSM 6 to 7 Migrations Each customer will have different desires with respect to field value transformation and mapping, Source and Target classes may be different, Historical requesters may not exist, Categorisations will be different. Migration Challenges

Project

Project Overview Data migration responsibility for end customer’s production migration weekend. BMC responsible for foundation data. Fixed Price Incidents, Changes, CMDB Work with customer, implementation team.

Project Milestones Production Data Summary Data Mapping Sessions Mapping Document Full Migration to Development Production Migration Migration Results Document

Production Data Summary Investigation of production server data. Interviews with client’s data managers. Human analysis using both ARS tools and scripted schema and query tools tailored for the client’s production dataset.

Data Summary

Data Summary

Data Mapping Preparation Client’s data managers select a set of “root request” records to be brought over. Migration scripts are tailored and run taking over the selected “root request” records’ well formed trees. Preparation

Data Mapping Sessions Held with client’s data managers once selected records brought over. Migrations of single, well formed trees take place during the session. Changes are made and results are immediate with a press of the refresh button. Sessions

Sessions

Data Mapping Documents “Human generated” from scripts All records read and output identified and listed. Field by field assignments listed. Mapping

Introducing Meta-Update Scripts

Introducing Meta-Update Meta-Update is a Remedy ARS Data Integration, Server sync, File Import, Export, Batch and Workflow tool. Meta-Update’s ROI is typically its first use. Scripts Meta-Update is a new way to harness the power of the ARS API: with no programming at all! Meta-Update shortens API development by 90%

Introducing Meta-Update creates repeatable, reliable harnessing the power of the API, with queries and assignments in a language your ARS Administrator already speaks. Scripts An ARS Administrator Command scripts, Query = Src, HPD:HelpDesk, ‘Customer Name’ = “$Fle, Cust$” AND ‘Name’ = “$Fle, NmL$, $Fle, NmF$”

References ARS:$Field$ Scripts A Tag is a reference to an ARS record, file record, SQL row, a named variable set, a diary entry, program arguments, the environment. Meta-Update:$Tag, Field$ A Field is an ARS field’s database name or id, a field defined from a file or SQL definition, a program argument, environment variable, assigned string variable name.
