FatalError: Cannot import site. Export / Import-SpWeb in SharePoint 2010

Error:
FatalError: Cannot import site. The exported site is based on the template STS#0 but the destination site is based on the template SPS#0. You can import sites only into sites that are based on same template as the exported site.


Import-SPWeb : Cannot import site. The exported site is based on the template STS#0 but the destination site is based on the template STS#1. You can import sites only into sites that are based on same template as the exported site.

Issue:-
In SharePoint 2010 when we use Powershell Commands to Export / Import site collections we get Site Template mismatch errors as now SP 2010 needs to have the same template for the site while importing which was used on the site exported.

In such scenarios when you have migrated from SPS 2003 -> MOSS 2007 -> SP 2010 there will be many old Site templates which are now Obsolete in SP 2010 and not available, due to which it will be very difficult to Import the site.

Resolution / Workaround:-
1. Central Admin -> Application Management -> Create Site Collection
2. During Template selection go to 'Custom' Tab -> Select Template Later.....
3. Run the Import-SpWeb command now and it should import the site collection without any issues.

As we are not selecting any template while creating a Site Collection, it automatically pics up the template which is using while importing the Site Collection.
