A site package is a portable snapshot of one domain's site. Use it to hand an agency demo over to a client's own instance, or to copy a site to another domain on the same server.
A package contains just that one site:
It deliberately leaves out plugins, instance settings and anything secret, so a package is safe to send to another instance and carries nobody else's data.
The manage_domains capability, plus access to the domain being moved. It is a
domain-management operation, not day-to-day content editing.
Applying overwrites the target site, so it always takes a safety snapshot first, and the change is recorded in content history where that is enabled - you can roll back.
A connected agent (Claude / an MCP client) has the tools and the recipe built in. You can simply ask, for example:
"Package the site on
demo.exampleand apply it toclienta.com."
Behind the scenes the agent follows the migrate-site recipe it gets from
describe_capabilities: site_backup on the source, then (if the instances
differ) download + upload, then site_apply on the target, then a preview to
confirm. It will ask you to register the target domain first if that is needed.
lazysite-site --docroot DIR backup --host demo.example
lazysite-site --docroot DIR apply --package lazysite-site-demo.example-<stamp>.tar.gz \
--host clienta.com --clean
--host on apply names the target domain (omit it to apply to the default
site); --clean clears the target content folder first.
lazysite moves the lazysite side of a site. DNS, the web-server domain alias and the TLS certificate for the new domain are the operator's / Hestia's job - set those up first, then apply the package. Use the domain Check on the Domains page to confirm DNS and HTTPS are in place.
