Fixed by Masa in Product. If a fix is needed for Magnolia, to be opened as MLF ticket.

Hi Masahito, I have emailed you on this request, as there is quite a lot to change. 

Hi c383681f6b03, Thanks for checking. I think you can update occurrences of "transition (移行)" to "トランジション" where switching issue status for consistency.

Hi @Masahito_Sugahara, hi @Ai Hirama thank you for following up. In terms of 'transition', could you let us know if there is a follow up action you want us to do? thanks.

agreed, thank you for checking them!

ahirama I checked our Jira Cloud TM and found out that both were used. The usage of トランジション seems to be more prominent, and more importantly for consistency, I agree that we should follow what has been used in our translation.
On a different note, I think "issue" should be "案件" rather than "課題" considering what it does, but our users will be confused if we suddenly change it, so we probably will need to stick to it.

1fa8f36b8478 I agree that this term is a bit tricky one. However, for moving the issue between statuses, トランジション has already been used for a long time, so using a different term suddenly may cause confusion to users

mheighway@atlassian.com they can be found in the workflow configuration screen of next-gen JSD projects

I am adding some context here as this is a touchy issue with this term.
This is not a mistranslation rather preferential, but we certainly hope to achieve consistency.
Please see the link below on how even Microsoft struggles to translate this term consistently:

Hi ahirama,

To help us update this term, could you let us know where you saw this word appearing?

Many thanks,

Melanie
