1) Make the safety OFFLINE copy of db80 and confg dirs for disaster recovery purpose
In old cell:
- omnistat (confirm no backup running)
- omnisv –stop (stop DP services)
- copy the “db80” and “config” folder
2) On the old cell, execute writedb of both CDB and MMDB
---start DP service: #omnisv –start
---check IDB and confirm works: #omnidbcheck –extended (will take 3-6 hours)
---write IDB to txt files: omnidbutil –writedb \database (will take 4-8 hours)
3) At the end of the writedb, copy the directories proposed by the writedb
Should be： <DP dir>\db80\dcbf
And: <DP dir>\db80\msg
4) Copy the CONFIG directory (with datalists, barlists, schedules, etc ...)
5) Write down (from omnidbutil –extendinfo) any IDB extension files
check and note down the number of existing extensions (fnames/fn/dcbf)
---In D:\ProgramData\OmniBack\db80\datafiles\Cdb
---omnidbutil –extendinfo > IDB.txt
6) Stop the DP, uninstall the DP from old location (If old and new are two hosts, please ignore this step)
7) Install the DP to the new disk / location
---Installed the DP agent and latest DP patches
8) Extend the IDB files, based on the info from step #5
In GUI—Internal database---usage---<right click> Database tablespace Extension—Add Database tablespace Extension files
9) Execute the readdb on the new IDB from the original files
--omnidbutil –readdb \database
10) Copy the dirs proposed by #3 to their new locations
<DP dir>\db80\dcbf
And: <DP dir>\db80\msg
11）Open GUI, testing everything works
copy the complete <DP_DATA_DIR>\config\server\idb\ dir from before overwrite
not only idb.config
12) Copy CONFIG folder content to the new location
13）copy back <DP_DATA_DIR>\config\server\idb\ dir in step12
14) restart DP services
15) omnidbutil -show_cell_name
16) omnidbutil -change cell_name <new name>
