Hi Manandeep ,
This can happen when the users own content on Tableau Server and Tableau won't allow you to remove a user without first changing the owner of the content (Workbook, Project, etc...)
Can we use the same 10.5 version license for version "2018.2" or do we need to upgrade/purchase a new license ?
Yes you can use the same license although you will need to pay annual maintenance charge to get tableau support periodically
Here are Tableau's new monthly prices: Tableau Desktop Personal, $35; Tableau Desktop Professional, $70 ; Tableau Server, $35; and Tableau Online, $42. Under the old model, a license, with annual maintenance, cost $999 for Desktop Personal and $1,999 for Desktop Professiona
Please mark the answer as CORRECT/HELPFUL if it really helped you so that it can help others as well
