Migrating from Multi-Select List to Enumeration List
Hello there,
What's the best way of updating a process template with the old Multi-Select List datatypes to the new Enumeration List.
Thanks.

Accepted answer
To my understanding, changing data type is not possible directly. I had tried a lame attempt to modify the configuration source but it dint go that well though I cannot recollect what was not it exactly.
However, one possible way could be to use child project areas.. Suppose you have a Multi-Select List Process Template, create the Parent Project Area PPA_M from it Create a replica process template delete the multi_select list add Enumeration List data typed attribute with same ID as the Multi-Select List Attribute from PPA_M Use this to enum typed process template to create new Parent Project Area E, PPA_E Enable Process Sharing in both the parent projects PPA_M, PPA_E. Now any child project CPA_ChangingAttribType of PPA_M will have Multi-Select List Attribute When you need to change the type, change parent of CPA_ChangingAttribType to PPA_E Since the attribute id's are same, the type should most likely, effectively change. Hope this gives the required solution or atleast some direction towards an answer. Cautionary Note : I have not tested this for any dependencies that might be affected..

Note: I once ran this past the RTC dev lead, and he warned me that this approach could produce errors, so it is not a supported approach. Hi Muktar, as mentioned in my solution, I have not tested it for hidden dependencies. Please exercise caution before using this solution. Importantly, as we see from Geoffrey's note, it is not a supported approach. |
