VPS vs shared hosting: check what an upgrade actually changes

Write an upgrade ticket before comparing plans

Instead of starting with a provider ranking, complete this sentence: “My current plan cannot do ___; the candidate plan explicitly permits ___; I will verify it by ___.” Keep a missing answer as Unconfirmed. A larger resource card is not the missing answer.

This worksheet is our proposed workflow. It records your own requirements and observations; its empty fields are intentional. It does not represent a test of your site or of a hosting service.

Example: you need a package that requires administrator access

This is an illustrative requirement, not a tested customer case. Put the package's actual installation requirement in the ticket. If it really requires root, a plan documented as having no root does not satisfy that requirement, even when its name contains VPS. If the software can instead run inside your user directory, investigate that route before assuming that administrator access is necessary.

DreamHost's root-access article explicitly discusses installing software in a user's home directory without root. That is a documented possibility, not proof that your particular package will work. Official source. Reviewed 2026-09-28.

Example: you want more predictable processing capacity

Write down the workload and the symptom first. Then compare the allocation policy of the actual candidate plans. Do not mark “exclusive CPU” confirmed merely because the page says virtual server. For a candidate with a shared-CPU policy, decide whether that policy meets your requirement instead of silently treating it as dedicated capacity.

The DigitalOcean distinction in the evidence table provides a concrete place to check that question. It does not establish the performance of a particular site. No latency, throughput or capacity measurement was performed for this article.

Example: the website moves, but the bundle does not

Make a dependency row for each service your site relies on: its website files, database, email and recovery copy. For each row, write “retained,” “moved,” or “replaced,” and identify who will check it. An unanswered email row is a migration question, not a reason to assume email continues unchanged.

Use separate acceptance checks: open the migrated site, test its essential interactions and verify the services you decided to retain. These are suggested checks, not claims that we completed your migration. DreamHost's instructions say to confirm that the site works on the destination before cancelling the old plan.

Turn the ticket into a decision

Stay for now when you have not identified a requirement that the current arrangement fails. Investigate a VPS when a candidate's documented capability addresses that requirement and you have an owner for the work. Pause the purchase when the deciding capability is still Unconfirmed. These are editorial decision options, not promises about cost or performance.

Keep the completed ticket with the evidence date. If the provider changes a plan, recheck the deciding capability rather than rewriting the whole decision around a new headline. Compare the plan against the original task, not against the excitement of a new specification.

Resolve an upgrade decision when the evidence disagrees

Use the following record beside the ticket. This is a proposed decision procedure, not a scoring system supplied by a host. Give each requirement its own row and keep the requirement unchanged while comparing candidates. Otherwise, a tempting specification can quietly change the question you were trying to answer.

A positive feature cannot cancel a contradicted requirement

Suppose your written requirement is administrator installation of a particular package. A candidate's documentation denies that permission, but its card offers more storage. Mark the permission row contradicted. Do not average the storage benefit against it or award enough points to make the candidate pass. The proposed upgrade has not solved the task that justified buying it. This example uses a hypothetical requirement, not a claim about a customer's installation.

A missing statement is a question, not a rejection

Suppose a candidate's documentation never addresses the permission your task needs. Record Unconfirmed, rather than supported or contradicted. Ask: “Does this exact plan permit this installation step, and which document describes that permission?” Save the answer with the same requirement row. If the response refers to another product, the row remains Unconfirmed. This prevents a generic answer about VPS hosting from becoming evidence for a different plan.

Documented permission and a successful trial are different records

A plan can document the permission while your application has not been tested there. Keep “supported / not tested” intact; do not shorten it to “works.” If a later trial fails, preserve the earlier document evidence and record the failed action beside it. The failure may require investigation, but it does not prove that the documentation was false. Conversely, a successful check of one action does not clear the untouched rows for email, recovery or other dependencies.

Write the conclusion so someone else can challenge it

Use this format: “We are considering this plan because it addresses this blocked action. The evidence is this document for this product. The remaining unchecked action is this one, assigned to this person.” A reviewer can now point to a particular unsupported step instead of arguing about whether VPS is better in general. Keep optional benefits outside the must-work rows so they cannot disguise a missing prerequisite.

When evidence changes, revise the affected row and its date, then repeat the conclusion. Retain the previous entry as history rather than overwriting it with a newer claim. This record makes the reason for staying on shared hosting, testing a candidate VPS or rejecting it inspectable without inventing a traffic threshold or a performance result.
