[rt-users] Transferring CustomField Values from old to new on all tickets in a queue

[Venkateswaran, Subbaraman]

Ken Thanks for your suggestions. Just thought of sharing the path we
took to fix this issue...
 
1. Basically we identified that one unique CF that we want across all
queues
2. Added it to the Queue
3. Ran a script to copy data from the old CF to the new CF on all
tickets in this queue. This we did it using a template that we found in
RT wiki
http://wiki.bestpractical.com/view/ImportCustomFieldValues
and basically used the HasEntry, AddCustomFieldValue methods from
objectcustomfieldvalues to accomplish this.
4. Detached the old CF from the Queue.
 
What we are planning is to do the same for all dup'ed CFs on all the
queue. Many one time effort but could pay us in long run on ease of
maintenance.
 
Thanks
Subba

Subbaraman,


    Yes. I've been thru this several times. Each time I found a better
way to do it. First off, you have to decide what the CF name will be for
ALL the queues that will be using it. Secondly, you have to have a
consensus on the values you will allow. Third, you create the NEW CF and
it's values. Now, if you have a CF that already exists and you want to
use it, then you still need to set up all the values. The last step is
to APPLY this particular CF to all the queues that will be using it.
Once that is done, set up some scripts (NOT scrips) that detail which
OLD CF"s should be WHAT VALUE for the NEW CF. Once that is done, you
execute each of those scripts for EACH queue by running a query to pull
ALL tickets of each queue (1 queue at a time) and use the "bulk update"
feature to set the new value for the new CF based on the
script/selection criteria for the OLD CF.
    For example. Let's say I have 3 CF's that are similar. I take CF1
and set up all the values I want it to have. If there are any values I
want to get rid of, I add the news ones first, then run a Search/Bulk
Update to change the values I want to get rid of to the new values.
Select all tickets where CF1 value = "X". Bulk Update the results to be
CF1 value = "Y". This would be the basic routine you walk thru for EACH
and EVERY value of CF2 and CF3 for Each Queue that uses CF2 and CF3, 1
Queue at a time.
    That should do it. There are no real shortcuts that I know of for
this kind of thing. You COULD use SQL and do this DIRECTLY to the
DataBase, but that get REAL messy and I do NOT recommend it.
    Hope this helps.

	We are using RT 3.6.4 and what we are trying to do is to
synchronize custom field across all queues and basically have one unique
custom field and type. Currently we have some CFs with the same name and
different types dupe'ed across all the queues. Is there a way we can
script around to move all the values from oldCF to new CF on all tickets
in a Queue ?

	For e.g.: 
	CF Name XYZ, Type: Enter multiple values 
	CF Name XYZ, Type: Text 
	Move all the values on XYZ(enter multiple values) to the CF
XYZ(Text) on all tickets in a Queue. 

	Once this is done we will disconnect the old CF XYZ(Enter
multiple values) from the Queue. 

	Thanks for your help
