I have two farms which are sharepoint on-premises 2013, that have the same license type which is "SharePoint Server with Enterprise Client Access License" license. but the farms' build numbers are different as follow :-
- First farm have the following build number:- "15.0.4569.1000"
- while the second farm have the following build number:- "15.0.4875.1000"
now i want to move some document libraries between the 2 farms, by exporting the document library using this command:-
Export-SPWeb -Identity "http://****/Marketing/" -ItemUrl "Shared Documents" -Path "c:\export4.cmp" -CompressionSize 1000 -IncludeVersions All -IncludeUserSecurity -Force –Verbose
and importing it using the following command:-
Import-SPWeb http://t*****/sites/ccc/n/ –Path "c:\export4.cmp" -IncludeUserSecurity –Verbose
but before doing so can anyone adivce if it is a risky operation if i do an export/import between 2 farms which have different farm build numbers. mainly i have the following 3 concerns/questions:-
let say i export the list from a lower farm version "15.0.4569.1000", and then i import the list in a higher farm version "15.0.4875.1000". could this cause the farm which i am importing the list into to be downgraded ? or specific features to be removed/downgraded ?
let say i export the list from higher farm version "15.0.4875.1000", and then i import the list in a lower farm version "15.0.4569.1000". could this cause the farm which i am importing the list into to be upgraded? or certain features or columns to be added/upgraded ?
or i should not be worried too much. As if the export/import works fine then everything should be safe ? and if the export/import fail then the farm configuration or other settings will not be affected ??
now from my previous experience doing a site collection backup/restore will not work unless the 2 farms are identical. and if the restore fails then nothing will negatively affect the farm. but in the export/import case seems it allow us to do export/import between different farm builds . but my question is if it is considered a risky operation or not ?
