either prior upgrade or during fresh installation, ACS will handle the Template registration automatically, by mounting the secondary store onto the
management server, copying the respective Templates to the store and then creating the `template.properties` file.

From ACS 4.20.3 and 4.22.1 onwards A starting MS that detects an
upgrade is needed but also sees mshost entries for MSses that are up,
will abort. If as an operator starting an MS you get the error
`Database upgrade is required but the management server is running in
a clustered environment.` during upgrade, check if you have stopped
all MSses in your environment and retry. If is still fails it might be
that an MS has stopped un-gracefully and you need to fix the DB-entry

I added an example, can you see if such is what you mean, @weizhouapache ?

for it. For example, make sure all MSses are stopped by checking the
hosts in the output of `select name from mshost where state <> ‘Down’`
and then, when all is safe, run `update mshost set state = ‘Down'`
