Any one can help please

Hi @Mohamed Shawky ,

The new server name will need to be added to the license. Email licensing@nintex.com with a list of all the web server names in the farm to have a new license generated.

When the new server is added, Sharepoint should deploy all solutions, including the Nintex solutions to the new server. If for some reason this does not happen you can manually deploy them from the solutions page in CA.

Thanks, Simon, for your Reply. 
but for more clarification about manually deploing the Soulutions if needed, should it be as per below article.

or it can be done by any order!?  

Hi @Mohamed Shawky,

Technically they can be deployed in any order but Nintex recommends the following order:
nintexcommon.wsp

nintexexternalconnection.wsp

nintexforms2019.wsp

nintexforms2019core.wsp

nintexworkflow2019core.wsp

nintexworkflow2019.wsp

nintexworkflow2019enterprisefeatures.wsp

Feel free to skip any of the solutions you don’t have or don’t use.
